can someone tell how to do the cross-correlation of two speech signals (each of 40,000 samples) in MATLAB without using the built-in function xcorr and the correlation coefficient? Thanks in advance. matlab signal-processing cross-correlation Share Improve this question Follow edited Oct 1...
Cross-correlation collapse all in page Syntax r = xcorr(x,y) r = xcorr(x) r = xcorr(___,maxlag) r = xcorr(___,scaleopt) [r,lags] = xcorr(___) Description example r= xcorr(x,y)returns thecross-correlationof two discrete-time sequences. Cross-correlation measures the similarity ...

Compute and plot the normalized cross-correlation of vectorsxandywith unity peak, and specify a maximum lag of10. n = 0:15; x = 0.84.^n; y = circshift(x,5); [c,lags] = xcorr(x,y,10,'normalized'); stem(lags,c) Input Arguments ...
Compute the cross-correlation on the GPU. cc = xcorr2(offsetTemplate,template); Return the result to the MATLAB® workspace usinggather. Use the maximum absolute value of the cross-correlation to determine the shift, and compare the result with the known shift. ...
Let us discuss examples of Matlab xcorr. Example #1 In this example, we will use the xcorr method to compute the cross-correlation between 2 vectors. The steps to be followed for this example are: Create a vector ‘a’ Create another vector ‘b’, with a shift of required units from ‘...

If the MATLAB Signal Processing Toolbox is available, a MATLAB routine called xcorr is available that does the same thing, but features a wider range of options. Crosscorrelation can be used for the problem in Example 2.13 to determine the similarity between a signal and a reference waveform ...
The normalized cross correlation computed in normxcorr2 is robust to differences in illumination between the template and input image. In the example below, two different outputs are obtained. The first is with the template and input image with the same intensiti...
r = xcorr(___,scaleopt)also specifies a normalization option for the cross-correlation or autocorrelation. Any option other than'none'(the default) requiresxandyto have the same length. example [r,lags] = xcorr(___)also returns the lags at which the correlations are computed. ...
