The command dimensions computes the size of a matrix. This command is equivalent to the Matlab[size] command.

Use dimensions for computing dimensions of Maple variables, and Matlab[size] for computing the dimensions of MATLAB variables.

If X is a string, then the size is computed using MATLAB.

Executing the dimensions command returns an integer list with n elements for an n-dimensional object. For example, a 3x4 matrix is two-dimensional, therefore a list with two elements is returned. Each element corresponds to the size of that dimension. For the 3x4 matrix, the returned list is [3, 4].
