Hi,
Let the large matrix of dimensions 2520x192x144 be ‘A’. To compare data related to a month for all years, the data is to be separated based on months and t-test is perfomed on each.
month_data=A(month_number:12:2520,:,:);
h=ttest(month_data);
For Example,
January_data=A(1:12:2520,:,:);
January_test=ttest(January_data);
This produces a matrix of dimension 1x192x144. Thus all months give 12 matrices.
