linalg::matdim -- dimension of a matrix

Introduction

linalg::matdim(A) returns the dimension of the matrix A, i.e., the number of rows and columns of A.

Call(s)

linalg::matdim(A)

Parameters

A - an m x n matrix of a domain of category Cat::Matrix

Returns

the list [m, n], where m is the number of rows and n is the number of columns of A.

Example 1

The dimension of the matrix:

>> A := matrix([[1, 2, 3, 4], [3, 1, 4], [5, 6]])
                             +-            -+
                             |  1, 2, 3, 4  |
                             |              |
                             |  3, 1, 4, 0  |
                             |              |
                             |  5, 6, 0, 0  |
                             +-            -+

can be determined by:

>> linalg::matdim(A)
                                  [3, 4]
