When multiplying wrong-sized matrix TOL does not give a warning.

[sdelfresno]

If I have two Matrix like this:

A [100x200]
B[200x100]
C[108x56]

Calculating A*B will be ok, but:
Calculating A*C will return a [0x0] matrix, but will give no warning at all.

Therefore, when A*C is done, I see no error and TOL keeps on running using
wrong results.

I would find it very useful a warning in case this situation is encountered.

Thanks.

In order to use the ordinary matrix product we must be sure that the number of
columns of Matrix A is equal to the number of rows of Matrix B.

If you try this code:

Matrix MA = Rand(100,200,0,100);
Matrix MC = Rand(200,56,0,100);
Matrix M_AxC = MA*MC; It works correctly

With Tol code given in the bug report we are using a number of columns of Matrix
"A" distinct of the number of rows of Matrix "C".

Maybe the bug you are trying to report is within another piece of code, or with
other values. If this is the case, please report it as a new bug.

There is no bug, but the warning when the matrix product returns a [0X0] matrix
does not appear, and it must in order to advice to user.

A fix for this bug is already avaliable on the cvs.
