The second of these indicates a conflict between CGI and (presumably) PDL::Complex. Both are apparently importing a function i() in your name space. When you put CGI and HTML generation on the side for the moment (not loading CGI and CGI::Carp, and modifying the code accordingly), you avoid the conflict. The complex matrix $matrixM is printed out fine for me after that change. Expect the number you specify as "2+1*i" to be printed as "[2, 1]". The output format isn't quite as intuitive as the input format.

I haven't followed your code further, except noting that it announces the inverse of $MatrixM, but prints its determinant.
