Problem 1441. Convolution Power
Create the convolution-power vector from initial vector x and power n. In other words, similar to the scalar case, raising to the n-th power means repeating the convolution on itself n times.
Assume that n is a non-negative integer and x is a row vector.
Examples:
convpower(1:5,0) ans = 1
convpower(1:5,1) ans = 1 2 3 4 5
convpower(1:5,2) ans = 1 4 10 20 35 44 46 40 25
Neither string operations nor interpolations are allowed!

Unfortunately the FFT based solution using a binary expansion of 'n' won't be Cody-optimal :-)
