raise ValueError(ERR_MSG)
ValueError:
Error, the current matrix is not positive definite.
I cannot extract a random ensamble.
If you want to skip this error,
consider calling the method ForcePositiveDefinite() before extracting the ensemble.

    It could also be a consequence of a sum rule not well imposed.
    Try to run Symmetrize() to force the sum rule.
