WebWe found that the latter command in Maple VR2 quickly consumes about 10 Megabytes of memory. The for loop is much more economical. The Maple FFT is invoked with FFT(mpow,omre,omim). The output replaces the input. So let's save the input first: saveomre := array(1..N); saveomim := array(1..N); for j from 1 to N do saveomre[j] := … WebRESUMO.
