Hi,
I suspect (from the PDL::Complex manual page) :
This module features a growing number of functions manipulating complex
numbers. These are usually represented as a pair "[ real imag ]" or "[
angle phase ]". If not explicitly mentioned, the functions can work
inplace _____(not yet implemented!!!)______ and require rectangular
form.
Cheers,
