WebP = nextpow2 (A) returns the exponents for the smallest powers of two that satisfy 2 p ≥ A for each element in A. By convention, nextpow2 (0) returns zero. You can use nextpow2 to pad the signal you pass to fft. Doing so can speed up the computation of the FFT when the signal length is not an exact power of 2.
