Witrynanextpow2 Exponent of next higher power of 2 collapse all in page Syntax P = nextpow2 (A) Description example P = 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.Witrynanextpow2 Next power of two Syntax p=nextpow2(A) Description p = nextpow2(A) (That is, pthat satisfies 2^p >= abs(A)). This function is useful for optimizing FFT operations, which are most efficient when sequence length is an exact power of two. If Ais non-scalar, nextpow2returns the smallest power of two greater than or equal to length(A). …
