@columns |

Number of columns in matrix object, series, or group.

When assigning to a matrix object:

Syntax: @columns(m)

m: matrix, vector, sym, series, group

Return: integer

When assigning to a series:

Syntax: @columns(m)

m: group

Return: integer

Examples

matrix m1 = @mnrnd(10, 3)

scalar sc2 = @columns(m1)

assigns the value 3 to the scalar object SC2.

series q = nrnd

group mygrp q r s t

vector g = @fill(@rows(q), @columns(mygrp))

creates a two-element vector G containing the number of rows of Q and the number of series in MYGRP.

series h = r / @columns(mygrp)

creates the series H equal to the series R divided by the number of series in the group MYGRP.
