388	Problem with adding matrices	Christian Paz	Víctor de Buen Remiro	"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"	defect	closed	normal		Math	head	critical	fixed
