Hello friends! Today, we will build a convolution calculator in MATLAB and understand the calculation behind its output. We will first work through two short sequences by hand, then implement the same operation with loops and compare our answer with MATLAB's built-in conv function. Convolution appears in digital filters, communication systems, image processing and the analysis of linear systems. It combines shifted, weighted contributions from two sequences. Multiplying corresponding samples once is not enough; each output sample contains a sum of products taken at different relative positions. Our calculator will accept finite, real-valued numerical vectors and their starting sample indices. It will return the full linear convolution, display correctly indexed plots and report the numeric ...
