Description: MATFOR FFT Visual Fortran program.
MATFOR Extensions, as implied in the name, are data or components external to MATFOR modules that can be used to add versatility to MATFOR programs. Currently there are two types of extensions available with MATFOR, they are MATLAB Interface and Tecplot FileIO. MATLAB Interface, a new feature in MATFOR 4.1, provides MATFOR users access to MATLAB functions so they can obtain functionality that has not been built into MATFOR. The ability of using MATLAB functions makes MATFOR an ideal tool for those who create prototypes using MATLAB, then do implementation in C++ and other programming languages. Through the use of MATFOR, users may perform quick results comparisons between MATLAB and other languages. -MATFOR FFT Visual Fortran program.MATFOR Extensions, as implied in the name, are data or components external to MATFOR modules that can be used to add versatility to MATFOR programs.

Description: This function is written to understand and/or explain an fft algorithm and usage of radix2 procedure.
This function take the signal which you want to find FFT, for m bit
you can also call the function without entering a signal or number of points, because there is default values for y and m which are
y = sin(2*pi*50*t)+sin(2*pi*120*t)
m=3
you can see the steps of order reversing used as built-in function but non others. you will also see the taking butterfly tree steps.
for more information read the help file of function.
in future this can be improve as selective radix or any other feature you suggest please notice me for any sugestion.
