I need to use a matrix A to create a matrix B
matrix a
A=[123;456;789]
matrix b
B=[1+2i 2+3i 3+4i;4+5i 5+6i 6+7i;7+8i 8+9i 9+10i]

I'm not sure exactly how you are expecting this to be done, but you could simply just do:
A = [1,2,3;4,5,6;7,8,9];
A_imaginary = [2*i,3*i,4*1;5*i,6*1,7*i;8*i,9*i,10*i];
B = A + A_imaginary;
if that's all you needed to do?
