How to interpret the output
Computes full linear convolution with implicit zero padding outside each sequence. Output index k sums input[i] times kernel[k-i]. Output length is n+m-1. Edge terms include padding; correlation uses a different alignment. No sampling-interval scaling is applied. Source checked 14 November 2026.
