Description

The following code

Matrix A = Rand(0,0,0,1);
Matrix x = Rand(0,0,0,1);
Matrix b = MinimumResidualsSolve(A,x);

output this:

<W>
Warning: [1] <W>Intento de multiplicaci&#65533;n de una matriz vac&#65533;a.</W>
</W>
<W>
Warning: [2] <W>Intento de multiplicaci&#65533;n de una matriz vac&#65533;a.</W>
</W>
Segmentation fault (core dumped)

This piece of code is solved but a general solution should be implemented which catch all possible exceptions from GSL.
