1. The problem statement, all variables and given/known data How do you turn the transformation matrix 1+i 3 2-i 5i into a diagonal matrix when it is transforming vectors in the Z module? What is the Z module? Normally one states R module M. where R is the coefficient one multiplies to the elements in the module. 3. The attempt at a solution I have tried but can't seem to reduce to diagonal form as I can only multiply by integer numbers?
