B' is 4x1 M is 4x4 then C=M*B' would be also 4x1. then you can not compute C*M since C is 4x1 and M is 4x4.
But you can compute C1=M*C and then C2=M*C1. Exactly as we are writing this.

that what i meant....C1=M*C and then C2=M*C1. and so on until one answer is repeated. i try to use for loop but it didn't work
