I want to define a matrix valued function: what is wrong with this code? s0 = matrix([[1,0],[0,1]]) sy = matrix([[0,-I],[I,0]]) r(theta) = cos(theta/2)*s0 - I*sin(theta/2)*sy
r(1) does not evaluate to r(theta=1) Thanks! -- You received this message because you are subscribed to the Google Groups "sage-support" group.
