Hello everybody, I have a 1x1 data structure which contains 144 fields (i.e. each field is a 26048x1 vector (double)). I need to find the correlation matrix of this data set (showing the correlation between vectors) and at the end, i need to plot it like the figure below:
be thankful for any idea!
Thanks

first step you have to construct the big matrix then compute the correlation:
X=struct2array(here type your structure title) % data
y=corrcoef(X) % correlation matrix
