Re: [Lapackpp-devel] Memory Allocation

[Christian S. <sti...@tu...>]

Hi Kevin,

can you provide some example code that demonstrates the error? 
Allocation itself usually is not a problem, even for much larger 
matrices (can be verified by ./matrix/testing/tgd 200 200).

However, it is true that lapackpp unfortunately doesn't check for 
successful allocation of a new matrix. I'll add this in CVS soon.

Regards,

Christian
