Convolution

This filter is a general 5x5 convolution filter with an extra dimension - time. It applies one matrix to the current frame, another matrix to the previous and yet another one to the frame prior to that. Settings Use output instead of input for previous frame: Determines which previous...

Shows graphically the various stages of discrete convolution for any two 1-D signals.This is for educational purposes really so the screens are optimized for signals of a few samples. Between two stages the figure pauses and requires the user to strike a key to continue. This should allow...

A GENERALAZED CONVOLUTION COMPUTING CODE IN MATLAB WITHOUT USING MATLAB BUILTIN FUNCTION conv(x,h)


Platforms: Matlab

This code computes the approximation of the convolution integral (*) between two functions, f(t) and g(t), sampled at the times t1,t2,...,tm (unit spacing), via the trapezoidal quadrature rule. To compute the integral with other than unit spacing, multiply the result by the spacing...

This function is an implementation of N-dimensional convolution for the special case when the convolution kernel is separable.A continuous function f(x1, x2, ... xN) is considered separable if there exist N functions f1, f2, ... fN such that f(x1, x2, ... xN) = f1(x1)f2(x2)f3(x3)...fN(xN).In two...

A function that takes two sequences(vectors) as parameters and computes the circular convolution .x(n),h(n) are the vectors.The vectors need NOT be of equal lengths.If they are of unequal lengths, the shorter vector is appended with trailing zeros and then circular convolution is carried out.

FASTRMS Instantaneous root-mean-square (RMS) power via convolution.FASTRMS(X), when X is a vector, is the time-varying RMS power of X, computed using a 5-point rectangular window centered at each point in the signal. The output is the same size as X and contains, for each point in X, an estimate...

CONV_MTX Convolution matrix. If 'x' is a column vector of length 'nx', then conv_mtx(x,nh) gives a toeplitz matrix 'X' of size (nx+nh-1) times (nh). 'nh' is the length of the column vector 'h' with which 'x' is convolved. Thus finally 'X*h' is same as conv(x,h). If 'x' and 'h' are row vectors,...
