lapack return values/error messages

[Miguel Morales]

Hi,

From what I can see, lapack calls in Slate do not have a returned value, which means that in general the users don't have the traditional way to tell what happened when a calculation failed, or even if it failed. What is the proposed way to obtained the standard information contained in lapack's INFO output?

best,

Hi Miguel,

Now SLATE LU returns info for exactly singular matrices, and Cholesky returns info for positive definiteness, as in LAPACK. See
