Parameters

signalLength  Int32

The length of the input signal.

signal  ReadOnlySpan<Complex<T>>

A read-only span containing the complex input signal.

signalStride  Int32

The stride between successive elements in the signal. Use 1 for contiguous data.

resultLength  Int32

The expected length of the result (should match GetOutputLength(Int32)).

result  Span<Complex<T>>

A span to store the convolution result. Must have capacity for at least resultLength elements.

resultStride  Int32

The stride between successive elements in the result. Use 1 for contiguous output.

Complex convolution computes: y[n] = Σ_m x[n - (m - a)] · h[m], where a is the anchor index. The operation preserves complex arithmetic throughout.

This method automatically selects between direct (time-domain) and FFT (frequency-domain) algorithms based on the ProcessingMethod setting and signal/kernel sizes.
