Let A and B be n × n matrices. in Linear Algebra We say that A is similar to B if there is an invertible n × n matrix P such that P−1AP = B. If A is similar to B, we write A ∼ B. Remarks. • If A ∼ B, we can write, equivalently, that A = PBP−1 or AP ...
so I want to know how we find similar matrixs and one matrix how many have a similar matrix and how we find their numbers?
