how to do correlation tests to a cell array

Hi,

I have a cell array with 24 cells. I am trying to write a correlation between the variables inside each cell. In each cell, there is a table with dimensions 20*20. How can I write efficiently a code to automate it? Right now, my for cycle returns me an error, so I am sure something must be changed/added.

for i=1:1:24
figure;
set(gcf,"Visible","on");
correlationP1= corr(mydada{1, i},"rows","pairwise","type","Pearson")
end

I thank you in advance,

Best regards
