dimensions

  

compute the dimensions of a MapleMatrix or MatlabMatrix using Maple

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

dimensions(X)

Parameters

X

-

MapleMatrix, or MatlabMatrix

Description

• 

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].

Examples

Setting two Maple matrices.

withMatlab:

maplematrix_aMatrix1,2,3,3,4,5

maplematrix_a123345

(1)

maplematrix_bMatrix8,7,6,3,2,1

maplematrix_b876321

(2)

The dimensions of these matrices in Maple are computed as

Matlabdimensionsmaplematrix_a

[2, 3]

Matlabdimensionsmaplematrix_b

[3, 2]

The matrices are set in the MATLAB® session

setvarmatlabmatrix_a,maplematrix_a

setvarmatlabmatrix_b,maplematrix_b

The product of maplematrix_a*maplematrix_b is computed in MATLAB® and the result is assigned to matlabmatrix_c. The dimensions of the new matrix are determined with the Maple call.

MatlabevalMmatlabmatrix_c = matlabmatrix_a * matlabmatrix_b
