Calculating correlation matrix from time series in an array
Show older comments
I have a cell array with 164 entities, each with an entry of 193X1 time points. I need to create a correlation matrix of the dimension 164X164 with pearson correlations. How can I go about doing that?

Use corrcoef() but first convert the matrix to correct form
C = % 164 elements cell array
Cv = [C{:}]; % creating a matrix
coff_matrix = corrcoef(Cv); % 164x164 matrix

That depends how are they stored. Are they stored in .mat file? How to you want to store the output?

Without more information about the content of each mat file (i.e., names of variables) and how they are stored, it is difficult to give an exact solution.
