square

  

determine whether a MapleMatrix or MatlabMatrix is square

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

square(X)

Parameters

X

-

MapleMatrix or MatlabMatrix

Description

• 

The square command returns a value of 'true' if X is a square matrix.  All constants are considered to be one-by-one square matrices.

• 

A cubic matrix is not square.  A square matrix can have at most two dimensions.

• 

Executing the square command returns a value of either 'true' or 'false'.

Examples

Setting a Maple matrix in MATLAB®.

withMatlab:

maplematrix_aMatrix1,2,3,3,4,5

maplematrix_a:=123345

(1)

maplematrix_bMatrix8,7,6,3,2,1

maplematrix_b:=876321

(2)

Determine whether these matrices are square.

Matlab[square]maplematrix_a

false

Matlab[square]maplematrix_b

false

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. Determine whether the new MatlabMatrix is square.

Matlab[evalM]matlabmatrix_c=matlabmatrix_a*matlabmatrix_b

Matlab[square]matlabmatrix_c

true
