First time poster here. I hope the question is fine, but please notify me in the comments or edit if sth is wrong with my question
The problem I’m facing is that my
if-statement isn’t evaluating, regardless of both the condition and both values evaluating correctly in Mathematica 9.0:
if[CoefficientList[Det[A - IdentityMatrixx], x] == CoefficientList[x^3,x], 2, 3, 3]
A is a square-matrix. The basic idea is to get a value based on a whether
A is nilpotent. The output I get is
if[False, 2, 3, 3]
Thanks captain obvious. Why don’t I get 3, as expected?
