How does matlab do convolution

Input vectors, specified as either row or column vectors. Subset of convolution, specified as one of these values: 'full' — Returns the full convolution. More About collapse all Convolution The convolution of two vectors, u and v , represents the area of overlap under the points as v slides across u. Algorithms The fimath properties associated with the inputs determine the numerictype properties of output fi object c : If either a or b has a local fimath object, conv uses that fimath object to compute intermediate quantities and determine the numerictype properties of c.

Wayne King on 27 Nov Vote 1. I take it when you say "without commands", you really are just saying without conv. It appears to me you have 1-D vectors from your initial post. Specifically, you give the example:. You can exploit the relationship between linear convolution, circular convolution, and the DFT by extending the length of your input vectors with zero-padding, multiplying their DFTs, and then taking the inverse DFT.
