Comment (by novoselt):

 Well, as I understand `is_positive_definite` can call the decomposition
 and return False if either it fails of there are negative entries. For
 this patch it seems that the purpose of both methods is exactly the same -
 if the underscore cannot compute the decomposition for whatever reason,
 this is the same reason that should be reported by the public method.
