# dollar

($) last index ### Description The $ symbol denotes the last index (row or column) of the array. It is therefore equal to the number of rows or columns.

The $ symbol is also used to LaTeX texts, which must start and end by $. See also math_rendering_features_in_graphic.

// Access the last element of second column, i.e. 8
b($,2) //Access the last element of b, i.e. 9 b($,$) // Add a row at the end of the matrix b b($+1,:) = [1 1 1]

// The $symbol as a LaTeX delimiter titlepage(['$\Huge\textrm{It is }\LaTeX:$';'$\Huge 2^2+1=\sqrt{25}\$'])
