Hello,

I'm using Sage to get random_matrix for Students.

random_matrix(QQ,4,4, algorithm="echelonizable", rank=4, upper_bound=15)

Is there an option to get all elementary matrices for all elementary matrix-operations by using for example matrix.inverse()?

Thanks for the help!

I don't understand the question. But this might be related:
