Fast convolution is a primary goal in real-time DSP applications. Here I provide three custon convolution computation functions, suitable for real signals only. Quite remarkably, they outperform MatLab's built-in conv.m function when the length of both sequences is greater than 2^12! I also provide a benchmarking script and some figures of my results. Even more suprisingly, there is no coding in a lower level language like C or assembly. Therefore great room for further speed improvements exists!
