Are you perhaps mixing up the column operator with the power operator? Is this what you are trying to do?

Why are you using the Matrix column operator in your definition of moduleqdcidc?

Aren't qdc and idc vectors?

If you have (as I think you do) an imaginary Number with real and imaginary parts, then your Modul function is simply the magnitude (use the absolute value icon). If you are doing it to every component of a vector, then you must "vectorize" it (Cntrl _) or you will get the magnitude of the whole vector.
