321 This document explains LyX's math features and is furthermore a collection
322 of LaTeX-commands used for mathematical characters and constructs.
323 The explanations are designed for the usage of commands.
324 It is therefore required that you have read the section
335 \begin_layout Standard
336 Most of the characters and many constructs explained in this manual are
337 also accessible via the menu
341 \SpecialChar \menuseparator
357 But everybody who has to write lots of formulas will notice that it is
358 much faster to use commands instead of the math toolbar.
359 Therefore this manual is focused on commands but also mentions the correspondin
360 g toolbar buttons when available.
363 \begin_layout Standard
364 If not specially mentioned the commands are only available within formulas.

4627 Specially for matrices there are ellipses that span over several columns.
4628 They are created with the command
4638 \begin_layout Plain Layout
4646 , that has the following scheme:
4649 \begin_layout Standard
4654 hdotsfor[distance]{number of columns}
4657 \begin_layout Standard
4658 The number of columns specifies how many columns should be spanned.
4659 Distance is a factor for the distance between the dots.
4662 \begin_layout Standard
4663 In the following matrix the command
4669 was inserted in the first box of the second line, to get an ellipsis with
4670 a dot distance twice as long as with the command
4677 \begin_inset Formula \[
4678 \left(\begin{array}{cccc}

4685 Note that the matrix fields that should be spanned must be empty, otherwise
4686 you get LaTeX-errors.

6451 \begin_layout Plain Layout
6461 , that don't add additional space.

6957 To omit a left or right bracket, a dot is inserted for the omitted bracket.

6985 \begin_layout Plain Layout
7001 \begin_inset Formula \[

7460 When brackets are needed that overlap each other, multiline formulas, as
7462 \begin_inset CommandInset ref
7464 reference "sec:Multiline-Formulas"
7469 \begin_inset Formula \begin{eqnarray*}
7470 A & = & \underbrace{gggg+bbqq}_{r}+\: dddd\\
7471 & & \hphantom{gggg+\:}\underbrace{\hphantom{bbqq+dddd}}_{s}\end{eqnarray*}
7475 In the first row the formula is inserted together with the first brace.
7476 It is hereby important that the space command
7480 \begin_layout Plain Layout
7481 Space commands are explained in
7482 \begin_inset CommandInset ref
7484 reference "sub:Predefined-Space"
7499 is inserted before the first
7500 \begin_inset Formula $d$
7503 , because the brace that ends behind the
7504 \begin_inset Formula $q$
7507 prevents that the following
7508 \begin_inset Quotes eld
7512 \begin_inset Quotes erd
7515 is surrounded by space.
7519 \begin_layout Plain Layout
7520 because a bracket is not handled as character, see
7521 \begin_inset CommandInset ref
7523 reference "sub:Binary-Operators"
7532 In the second row the second brace is inserted.

7549 \begin_layout Plain Layout
7557 \begin_inset CommandInset ref

7568 This space is needed because the

7576 is also surrounded by space in the formula.
7577 The brace is placed under the command
7586 \begin_layout Standard
7587 It gets more complicated when brackets overlap each other, like in the following
7592 \begin_layout Plain Layout
7604 \begin_inset Formula \begin{eqnarray*}
7605 & & \hphantom{gggg+\:}\overbrace{\hphantom{bbqq+dddd}}^{s}\\
7606 A & = & \underbrace{gggg+bbqq}_{r}+\: dddd\end{eqnarray*}
7614 \begin_layout Plain Layout
7625 The first formula row is the same as the second row of the previous example,
7626 with the difference that the brace is above.
7627 The second row contains the formula together with the second brace.
7628 To avoid that there is space between the upper brace in the first row and
7629 the formula, the row spacing need to be reduced.
7630 This is not easily possible due to a bug in LyX
7634 \begin_layout Plain Layout
7635 \begin_inset CommandInset href
7637 name "LyX-bug #1505"
7638 target "http://bugzilla.lyx.org/show_bug.cgi?id=1505"
7648 As solution for the problem, the global formula row separation
7658 \begin_layout Plain Layout
7666 must be changed to -6
7667 \begin_inset Space \thinspace{}
7670 pt before the formula with the command

9937 Another advantage to
9943 is that umlauts can directly be converted to mathematical text because
9944 the accent commands above are
9950 in mathematical text
9953 To convert an accented character to mathematical text, only the character
9954 under the accent may be converted.
9955 This applies also for all other conversions, e.

15697 Limits in displayed formulas are set above or below the operator, except
15698 of integral limits.

15702 To force that the limits are set beside the operator, the cursor is set

15729 The default limits type is this:
15730 \begin_inset Formula \[

15735 This is how it looks when the limits type was changed to
15742 \begin_inset Formula \[
15743 \sum\nolimits _{x=0}^{\infty}\frac{1}{x^{2}}\]
15747 For integrals, except of
15759 , the limits are by default set beside the operator.
15760 But for multiple integrals the limits are often set below the operator.
15761 In the following example the limits type was therefore set to
15765 and so set below the integrals:

15962 there can be too much space beside an operator, because the characters
15963 following the operator are set beside the limits.
15966 \begin_layout Standard
15967 To avoid this, the following macro can be used in the LaTeX-preamble:

23875 \begin_inset Formula $sin$

24452 Functions ! self-defined
24460 \begin_layout Standard
24461 To use a function that is not predefined, like for example the sign function
24462 sgn(x), there are two possibilities:
24465 \begin_layout Itemize
24466 Define the function by inserting the following line to the LaTeX-preamble
24470 \begin_layout Plain Layout
24475 DeclareMathOperator
24478 \begin_inset CommandInset ref
24480 reference "sub:Self-defined-Operators"

24518 DeclareMathOperator
24524 \begin_inset Newline newline
24528 \begin_inset VSpace -2mm
24532 \begin_inset Newline newline
24535 Now the new defined function can be called with the command
24544 \begin_layout Itemize
24545 Write the the formula as usual, mark the formula name, in our example the
24550 , and change it to mathematical text.
24551 At last a space is inserted between prefactor and function.
24554 \begin_layout Standard
24555 The result is the same with both methods as with a predefined function
24559 \begin_layout Plain Layout

29982 In this example the command

30001 was inserted to the formula.
30004 \begin_layout Standard
30013 \begin_layout Plain Layout

30037 To restart the formula numbering with new document parts or sections, the

30120 To be able to use these commands in TeX-mode, the

30128 character has to be made
30129 \begin_inset Quotes eld
30133 \begin_inset Quotes erd
30136 for LaTeX using the command
30150 So the command sequence in TeX-mode is:
30153 \begin_layout Standard
30159 \begin_inset Newline newline
30164 @addtoreset{equation}{section}
30165 \begin_inset Newline newline

30232 \begin_layout Plain Layout

30325 Sometimes formulas should be numbered in the following form:
30328 \begin_layout Standard

30334 \begin_layout Standard
30335 The formula number should start with every section with
30336 \begin_inset Quotes eld

30346 \begin_layout Standard
30347 For this case there is the command
30357 \begin_layout Plain Layout
30365 , which is used with the following scheme:
30368 \begin_layout Standard
30373 numberwithin{counter}{sectioning}
30376 \begin_layout Standard
30377 Counter denotes what kind of numbering is affected, sectioning denotes what
30378 number is before the dot.
30381 \begin_layout Standard
30382 Thus in our case the following LaTeX-preamble or ERT line is used:
30385 \begin_layout Standard
30390 numberwithin{equation}{section}
30393 \begin_layout Standard
30394 This is the result:
30398 \begin_layout Plain Layout

30439 To go back to the standard numbering or to prevent this kind of numbering
30440 when it is defined by the document class, the following command is inserted
30441 as ERT or to the LaTeX-preamble:
