309 \begin_layout Standard
310 This document explains LyX's math features and is furthermore a collection
311 of LaTeX-commands used for mathematical characters and constructs.
312 The explanations are designed for the usage of commands.
313 It is therefore required that you have read the section
324 \begin_layout Standard
325 Most of the characters and many constructs explained in this manual are
326 also accessible via the menu
330 \SpecialChar \menuseparator
346 But everybody who has to write lots of formulas will notice that it is
347 much faster to use commands instead of the math toolbar.
348 Therefore this manual is focused on commands but also mentions the correspondin
349 g toolbar buttons when available.
352 \begin_layout Standard
353 If not specially mentioned the commands are only available within formulas.
354 To be able to use all commands explained in this document, the option

892 In TeX-mode no command is needed to get TeX-braces.
893 TeX-braces don't appear in the output.
896 \begin_layout Standard
897 When commands without arguments, like commands for symbols are entered in
898 TeX-mode, a space character must
902 be behind the command to end it.
903 This space doesn't appear in the output.
904 When the space should appear in the output, the space must be followed
905 by a protected space in normal text.

4782 Specially for matrices there are ellipses that span over several columns.
4783 They are created with the command
4793 \begin_layout Plain Layout
4801 , that has the following scheme:
4804 \begin_layout Standard
4809 hdotsfor[distance]{number of columns}
4812 \begin_layout Standard
4813 The number of columns specifies how many columns should be spanned.
4814 Distance is a factor for the distance between the dots.

4818 In the following matrix the command
4824 was inserted in the first box of the second line, to get an ellipsis with

4840 Note that the matrix fields that should be spanned must be empty, otherwise
4841 you get LaTeX-errors.

7610 When brackets are needed that overlap each other, multiline formulas, as

7619 \begin_inset Formula \begin{eqnarray*}
7620 A & = & \underbrace{gggg+bbqq}_{r}+\: dddd\\
7621 & & \hphantom{gggg+\:}\underbrace{\hphantom{bbqq+dddd}}_{s}\end{eqnarray*}
7625 In the first row the formula is inserted together with the first brace.
7626 It is hereby important that the space command
7630 \begin_layout Plain Layout
7631 Space commands are explained in
7632 \begin_inset CommandInset ref
7634 reference "sub:Predefined-Space"
7649 is inserted before the first
7650 \begin_inset Formula $d$
7653 , because the brace that ends behind the
7654 \begin_inset Formula $q$
7657 prevents that the following
7658 \begin_inset Quotes eld
7662 \begin_inset Quotes erd
7665 is surrounded by space.
7669 \begin_layout Plain Layout
7670 because a bracket is not handled as character, see
7671 \begin_inset CommandInset ref
7673 reference "sub:Binary-Operators"

7699 \begin_layout Plain Layout
7707 \begin_inset CommandInset ref

7718 This space is needed because the

7726 is also surrounded by space in the formula.
7727 The brace is placed under the command
7736 \begin_layout Standard
7737 It gets more complicated when brackets overlap each other, like in the following
7742 \begin_layout Plain Layout
7754 \begin_inset Formula \begin{eqnarray*}
7755 & & \hphantom{gggg+\:}\overbrace{\hphantom{bbqq+dddd}}^{s}\\
7756 A & = & \underbrace{gggg+bbqq}_{r}+\: dddd\end{eqnarray*}
7764 \begin_layout Plain Layout
7775 The first formula row is the same as the second row of the previous example,
7776 with the difference that the brace is above.
7777 The second row contains the formula together with the second brace.
7778 To avoid that there is space between the upper brace in the first row and
7779 the formula, the row spacing need to be reduced.
7780 This is not easily possible due to a bug in LyX
7784 \begin_layout Plain Layout
7785 \begin_inset CommandInset href
7787 name "LyX-bug #1505"
7788 target "http://bugzilla.lyx.org/show_bug.cgi?id=1505"
7798 As solution for the problem, the global formula row separation
7808 \begin_layout Plain Layout
7816 must be changed to -6
7817 \begin_inset space \thinspace{}
7820 pt before the formula with the command

15894 Limits of inline formulas are set right beside the operator.
15895 Limits in displayed formulas are set above or below the operator, except
15896 of integral limits.
15899 \begin_layout Standard
15900 To force that the limits are set beside the operator, the cursor is set

15925 The default limits type is this:
15926 \begin_inset Formula \[

15931 This is how it looks when the limits type was changed to
15938 \begin_inset Formula \[
15939 \sum\nolimits _{x=0}^{\infty}\frac{1}{x^{2}}\]
15943 For integrals, except of
15955 , the limits are by default set beside the operator.
15956 But for multiple integrals the limits are often set below the operator.
15957 In the following example the limits type was therefore set to
15961 and so set below the integrals:

16160 there can be too much space beside an operator, because the characters
16161 following the operator are set beside the limits.

24220 In general, variables are set
24224 in mathematical expressions, but not function names, because
24225 \begin_inset Formula $sin$
24228 could be misunderstood as
24229 \begin_inset Formula $s\cdot i\cdot n$
24233 Therefore there are predefined functions, that are additionally a bit separated
24235 They are inserted as commands starting with a backslash before their name.

24796 \begin_layout Standard
24797 To use a function that is not predefined, like for example the sign function
24798 sgn(x), there are two possibilities:
24801 \begin_layout Itemize
24802 Define the function by inserting the following line to the LaTeX-preamble
24806 \begin_layout Plain Layout
24811 DeclareMathOperator
24814 \begin_inset CommandInset ref
24816 reference "sub:Self-defined-Operators"

24854 DeclareMathOperator
24860 \begin_inset Newline newline
24864 \begin_inset VSpace -2mm
24868 \begin_inset Newline newline
24871 Now the new defined function can be called with the command
24880 \begin_layout Itemize
24881 Write the the formula as usual, mark the formula name, in our example the
24886 , and change it to mathematical text.
24887 At last a space is inserted between prefactor and function.
24890 \begin_layout Standard
24891 The result is the same with both methods as with a predefined function

29989 \begin_layout Plain Layout
29998 \begin_inset Formula \begin{equation}
29999 A+B=C\tag{something}\label{eq:tag}\end{equation}
30003 In this example the command

30022 was inserted to the formula.
30025 \begin_layout Standard
30034 \begin_layout Plain Layout
30045 is inserted instead, the star prevents the parentheses around the expression:

30149 character has to be made
30150 \begin_inset Quotes eld
30154 \begin_inset Quotes erd
30157 for LaTeX using the command

30185 @addtoreset{equation}{section}
30186 \begin_inset Newline newline

30346 Sometimes formulas should be numbered in the following form:
30349 \begin_layout Standard

30356 The formula number should start with every section with
30357 \begin_inset Quotes eld

30367 \begin_layout Standard
30368 For this case there is the command
30378 \begin_layout Plain Layout
30386 , which is used with the following scheme:
30389 \begin_layout Standard
30394 numberwithin{counter}{sectioning}
30397 \begin_layout Standard
30398 Counter denotes what kind of numbering is affected, sectioning denotes what
30399 number is before the dot.
30402 \begin_layout Standard
30403 Thus in our case the following LaTeX-preamble or TeX-Code line is used:
30406 \begin_layout Standard
30411 numberwithin{equation}{section}
30414 \begin_layout Standard
30415 This is the result:
30419 \begin_layout Plain Layout

30459 \begin_layout Standard
30460 To go back to the standard numbering or to prevent this kind of numbering
30461 when it is defined by the document class, the following command is inserted
30462 as TeX-Code or to the LaTeX-preamble:

34318 \begin_layout Standard
34319 In some cases you might want to insert text characters directly into formulas.
34320 When for example the centered dot · is often used in formulas like
34321 \begin_inset Formula $\nu=5·10^{5}\,\mathrm{Hz}$
34324 , one would have to insert the command
34334 \begin_layout Plain Layout
34336 \begin_inset CommandInset ref
34338 reference "sub:Binary-Operators"
34347 all the time, because this character is defined in all encodings as text
34349 But the encoding can be changed by this LaTeX-preamble line:
34352 \begin_layout Standard
34357 Declare Inputtext{183}{
34367 f\SpecialChar \textcompwordmark{}
34371 \begin_layout Standard
34372 The character encoding (menu
34374 Document\SpecialChar \menuseparator
34375 Settings\SpecialChar \menuseparator
34378 ) specifies what character appears when a keyboard key is pressed.
34379 When the key for the character '·' is pressed, internally the command
34386 But this command is not available in a formula so that you would get LaTeX-erro
34388 With the changed encoding the right command is chosen automatically, depending
34389 on if the character was inserted into a formula or not.
34392 \begin_layout Standard
34393 The encoding of several characters is saved in definition files.
34394 Fore example the encoding
34398 is defined in the file
34402 that is in the installation folder of LaTeX.
34403 Encodings should only be changed via the LaTeX-preamble and not in the
34405 Otherwise own documents could not be edited by other LyX users working
34406 on other computers.
