{|
|-
|rand
|A linear random number generator in the interval [<nowiki>-</nowiki>1,1[
|-
|rand(seed)
|Like rand, except if seed is >0, it is used to initialise the generator.
|-
|rand(seed, <var>nr</var>, <var>nc</var>)
|Create a vector or a matrix with a linear random number generator with the interval [<nowiki>-</nowiki>1,1[.{|
|-
|<var>seed</var>
|the start value (if > 0)
|-
|nr
|the number of rows or elements (>=1; def.=1)
|-
|nc
|the number of columns (>=1; def.=1)
