Hi. I am new in Sage, so please accept my apologies if my question is basic.

Let $L=[A1,A2,A3,...,A100]$ be a list of non-negative matrices. I want to find a list that contains all positive matrices. Thanks in advance.

[A for A in L if min(map(min,A))>0] should do the job.

Thank you for your comment!
