compute the size of a MapleMatrix or MatlabMatrix using MATLAB(R)
MapleMatrix, or MatlabMatrix
The size command computes the size of a matrix using MATLAB®.
Executing the size command returns an integer list with n elements for an n-dimensional object. For example, a three-by-four matrix is two-dimensional, and returns a list with two elements. Each element represents the size of the corresponding dimension. The three-by-four matrix returns the list [3, 4].
To compute the size of a Maple variable, you should use Matlab[dimensions]. Calling size when X is a Maple variable causes X to be copied into the MATLAB® memory space before the MATLAB® size command is called. If X is already a MATLAB® variable (that is, X is a string), then the size is immediately and efficiently computed.
Setting two Maple matrices.
maplematrix_a ≔ Matrix⁡2,3,1,2,3,3,4,5
maplematrix_b ≔ Matrix⁡8,7,6,3,2,1
The size of these matrices in Maple is computed as
The matrices are set in the MATLAB® session
The product of maplematrix_a*maplematrix_b is computed in MATLAB® and the result is assigned to matlabmatrix_c. The size of the new matrix is determined with the Maple call.
