Options

The adaptation of the C-library is done in ./include/options.h. One chooses between window functions by defining one of the following constant symbols: KAISER_BESSEL, SINC_2m, GAUSSIAN, B_SPLINE.

Furthermore, the fast transforms can be instrumented such that the elapsed time for each step of Algorithm 1 and 2 is printed to stderr, respectively. This option should help to customise the library to one's needs. One can enable this option by defining MEASURE_TIME in options.h.
