Problem with adding matrices

Description

Hi,

This code gives a very strange result in TOL:

Set ab=SetOfMatrix(Matrix a = Col(0,1), Matrix b = Col(2,3));
Matrix c = Col(2,3);

Matrix e = BinGroup("+", ab);

Up to here e= [2 4] That's ok

Matrix f = c + e;
Mistaken result: (4.718282 5.718282)!!!!

Matrix g = e + c;
Correct result..

I suppose it is concerned with another error:

Matrix d = c + BinGroup("+", ab);

Gives a "Text is not a valid type for Matrix" error message. I think the
BinGroup is the error because declaring the matrix directly as "Matrix
c=Col(2,4);" gives the expected result.

Thanks,
Christian
