* Added keyword `method` to `correlate` function similar to [scipy correlate](https://docs.scipy.org/doc/scipy/reference/generated/scipy.signal.correlate.html) * If `method == 'auto'` method is choosing automatically between `direct` and `fft` * Added implementation of fft-based correlation * fft-based implementation may have accuracy issues, so it is validated in non-standard way. Depends on: #2180, #2202 --------- Co-authored-by: Anton <[email protected]>

FFT implementation validate arrays for supported strides/dtypes and if needed make a copy and cast (
_copy_array).Old implementation didn't validate for dtype in case of negative strides resulting in incorrect type selection in
_commit_descriptorand failures on systems withoutfloat64support.
