This function implements Linear Convolution by Overlap and Save method. It is fully optimized such that the main loop is not allocating. The function automatically computes the optimal DFT window.

The function has 3 output modes - Full, Same and Valid to match MATLAB's conv() function.

Th package contains also an implementation in frequency domain and performance comparison to the other 2 methods.
