28 Numbering and Labeling equations
31 Alejandro Aguilar-Sierra
34 A simple equation can be numbered by two ways.
35 The first is invocating the LyX command
40 The corresponding number
48 mark since true numbering is not yet implemented.
50 will appear after the right end of the equation.
65 Usually the equation number will be referred to in the document.
66 It's safer to assign a label to the equation, instead of using a fixed
68 Assigning a label to a non-numbered equation will make it numbered automaticall
74 we can be refer to the equation (
75 \begin_inset LatexCommand \ref{planck}
94 In the case of an equation array, every line is sequentially numbered.
95 It's possible to suppress the number for a single line with the command
101 The cursor must be at the row you want not to be numbered.
107 (x+y)(x-y) & = & x^{2}-xy+xy-y^{2}\nonumber \\
116 It's possible to label more than one line.
117 From the following array of equations we can refer to the equations (
118 \begin_inset LatexCommand \ref{eq:gs1}
123 \begin_inset LatexCommand \ref{eq:gs2}
127 ) using their corresponding labels.
133 v_{k+1} & = & w_{k}+b_{1}\label{eq:gs1} \\
134 w_{k+1} & = & v_{k+1}+b_{2}
