Description:

Create a multidimensional matrix where all the elements are1.

Syntax:

Note:

An external library function where ni defines sizes of dimensions in order. The function creates a new n*n square matrix when there is only one parameter n.

Parameters:

ni

A positive integer

Return value:

A sequence

Example:

 

A
