Today I used Scilab to generate a discretized sine wave and save the data into a CSV (comma separated value) file. The CSV file was then processed by a Python script that stripped away the commas and put each data element on a new line. The processed data file was then fed into my Fortran program that read the file in and performed a discretized fast Fourier transform on the data, and output the magnitude into a text file. The magnitude text file contained one data element per line. Finally, the magnitude data file is plotted using GNUplot to assess whether the results of the entire operation make sense.
