@Kitonum Hi, 

I just wanna test the equivalence ( equivalence = one can be obtained from other by interchanging rows or columns / or by multiplying -1 (negation)) of two Hadamard matrices .

Does the command is right one for that :

is(LinearAlgebra[Rank](A) = LinearAlgebra[Rank](B) and op(A)[1 .. 2] = op(B)[1 .. 2]);

@Carl Love Actually I want whether one matrix can be obtained from the other by some row /column operation 

or not.

@Carl Love I;had written in Windows Os ,maple 18 but I need to open this Linux,maple 16 . When I click to open this file it shows ":

Please help.

@Erfan Sorry, in Maple window my command is alright  ,i.e KroneckerProduct(A,B); 

Please find my worksheet reply here 

with(LinearAlgebra);
A := Matrix(3, 3, shape = Circulant[1, 2, 3]);
Matrix(%id = 4500888642)
B := Matrix(3, 3, shape = Circulant[x, y, z]);
Matrix(%id = 4500889218)
KroneckerProduct(A, B);

Error, (in `index/Circulant`[1, 2, 3]) improper op or subscript selector

@Kitonum  Sorry it doesnt work. 

with(LinearAlgbera):

A:= Matrix(3,3,shape=Circulant[1,2,3]);

B:= Matrix(3,3,shape=Circulant[x,y,z]);

KroneckeProduct(A,B); // KroneckeProduct[A,B]............none works.
