This MATLAB function plots Pearson's correlation coefficients between all pairs of variables in the input matrix of time series data.
How can we plot the correlation between pixels in two images, the first clear and the other containing noise, or correlation between the samples in two sound signals? Is there a tool in Matlab or a function that achieves this purpose?

A scatterplot matrix is the visual companion of a correlation matrix that shows all pairwise coefficients of correlation between variables. From: Knowledge Is Power in Four Dimensions : Models to Forecast Future Paradigm, 2022 About this pageSet alert ...
My question is, how can I then find the areas in this correlation plot that have a p-value < 0.05? I have tried this: ThemeCopy XX = []; fors = 1:316 forq = 1:332 [r,p]=corrcoef(squeeze(annual_snowfall_matrix(s,q,:)),squeeze(annual_mean_sie(s,q,:))); ...
Macmillan, 1988.这是这个函数的注释，按他说的这个是求C(m) = E[A(n+m)*conj(B(n))] = E[A(n)*conj(B(n-m))]。matlab自带很多函数，如果碰到不知道的可以直接在help里查看用法，也可以直接在命令窗口输入edit fun，比如edit xcorr，有时候可以看到函数源代码。这个就可以看到源代码。
An alternative implementation consists of using the Matlab built-in function qr, which can be used to generate the chain of variables in a computationally efficient manner.42 By default, the qr function adopts the column with the largest norm as the starting vector. However, a scaling procedure...
The bagplot visualizes the location, spread, correlation, skewness, and tails of the data. It is equivariant for linear transformations, and not limited to elliptical distributions. Software for drawing the bagplot is made available for the S-Plus and MATLAB environments. The bagplot is ...
We describe a novel method of kinetic analysis of radioligand binding to neuroreceptors in brain in vivo, here applied to noradrenaline receptors in rat brain. The method uses positron emission tomography (PET) of [11C]yohimbine binding in brain to quant
