FFTW Comparison

It has been our aim to use the FFTW FFT algorithm available at www.fftw.org/ in an OOMMF simulation and compare the results with a simulation using the OOMMF FFT routine.

The modification which was made to the original file containing the OOMMF FFT routine(in /app/mmsolve/) can be found in the following file:


The changed lines have been appropriately commented.

The following document describes the observations of this comparison:
