Fourier transforms (numpy.fft)¶
1-dimensional¶
| fft (a[, n, axis]) | Compute the one dimensional fft on a given axis. |
| ifft (a[, n, axis]) | Compute the one-dimensonal inverse fft along an axis. |
2-dimensional¶
| fft2 (a[, s, axes, -1)) | Compute the 2-D FFT of an array. |
| ifft2 (a[, s, axes, -1)) | Compute the inverse 2d fft of an array. |
N-dimensional¶
| fftn (a[, s, axes]) | Compute the N-dimensional Fast Fourier Transform. |
| ifftn (a[, s, axes]) | Compute the inverse of fftn. |
Hermite symmetric¶
| hfft (a[, n, axis]) | Compute the fft of a signal which spectrum has Hermitian symmetry. |
| ihfft (a[, n, axis]) | Compute the inverse fft of a signal whose spectrum has Hermitian symmetry. |
Real-valued¶
| rfft (a[, n, axis]) | Compute the one-dimensional fft for real input. |
| irfft (a[, n, axis]) | Compute the one-dimensional inverse fft for real input. |
| rfft2 (a[, s, axes, -1)) | Compute the 2-dimensional fft of a real array. |
| irfft2 (a[, s, axes, -1)) | Compute the 2-dimensional inverse fft of a real array. |
| rfftn (a[, s, axes]) | Compute the n-dimensional fft of a real array. |
| irfftn (a[, s, axes]) | Compute the n-dimensional inverse fft of a real array. |
