Errors in addition in matrix

[César Pérez Álvarez]

If we run this code

Matrix a = Rand(1,1,1,1);
Matrix b = Rand(1,2,2,1);
Matrix c = a+b;

We obtain a massage like this:

Imposible sumar dos matrices de dimensiones (1,1) y (1,2).

However the matrix c is a (1,1) matrix with MatDat(c, 1, 1) = 1.

I think that matrix must not be created.

We are working about thid bug
Thanks to report it

You want that an algebraic fail cause a syntax effect and that is quite debatable.

Afterwords, the change that you propose supposes to lose compatibility backwards and it is not easy to know the consequences that could have. It is necessary to put under it the analysis of the developers of tol-project.

I propose to return the unknown matrix.

[César Pérez Álvarez]

Return the unknown matrix it's ok for me. And put a warning it will be better too.

[danirus]

I'm agree with the final decision.
It's a syntactically well formed Tol sentence, and must be accepted without errors. The result must be arranged by Matrix Algebra.

Problem has been fixed in CVS

When a forbidden matrix operation is detected the Unknown Matrix 0x0 will be returned

A new test has been added to tol_tests/tol/Bugzilla/bug_000445
