Computes the fast Fourier transform (FFT).
c = fft(a)
c = fft(a, b)
c = fft(a, b, d)
c = fft(a, , d)
Scalar or array of any dimension.
Number of rows of a to use. If b is larger than the size of a, a is resized and padded with zeros. b is an integer and is typically a power of 2.
Dimension of a in which MathScript performs the FFT. d is an integer.
Tells MathScript that you want to specify a and d but not b.
Fast Fourier transform of a. Array with the same size as a, except you define a specific dimension. If you specify d, the size of c is the specified dimension. If a is a vector, c = fft(a) returns the original discrete Fourier transform (DFT). If a is a matrix, c = fft(a) returns the column-wise fast Fourier transforms of all columns of a.
A = [1, 2, 3, 4, 4, 3, 2, 1] C = fft(A, 8)
