the program is used to find out the FFT using time in decimation and solves problem of dsp fft ,compared with inbuilt fft and goertzel function , working well given with output also.
Defines and Computes the Differentiation Kernel, the kernel of the inverse heat conduction problem as a function of s and r. Note: you will need to select some value Nmax at which to terminate the infinite sums in SVE of the kernel
