Re: Real and complex arrays

I have a problem with real and complex arrays in fortran. I have a

abs(signalComplex) to get the magnitudes, and apparently abs() also

Your compiler is defective. ABS should return real for complex
arguments. If you assign to a complex array, though, you will
get complex numbers with imaginary part 0.0.

I can
live with that, but is there a way to get all these magnitudes (which
are now listed as real parts of a complex array) into a real array
(i.e. "dimensioned")? Or must I work with the complex array from now
on?

PS I have tried the real(complexNumber) command, but it just returns 0,
and not the real part formatted as a real number?


REAL() should return the real part of a complex number.

Can you tell us which compiler it is?
