Hi there!
I recently noticed the following problem: If I compute the minimal graded free resolution of a module via the Res() command,
I am able to make the matrices occuring in this resolution visible using the command Describe It;. But, I do not know how to
obtain a CoCoA List containing these matrices. This would be quite useful if one wants to use a particular matrix of the resolution in a further programming code.
Is there a way to get rid of this problem?
With best regards,
Almar

Try Code: R := Res(I);
Untagged(R);
