Your question is not clear to me. If you just want to access your cell array.

load('vims.mat');
f{1}(2,3) %first cell, row 2 column 3
ans = -0.5459

You could use cell2mat to convert the 5x1 cell-array with elements n_j x 3 into a matrix with n_many x 3 and then proceed as per usual with regular matrices. Or you could handle each cell-element at a time:

for i1 = 1:size(vims,1)
  currArray = vims{i1};
  % the operations you want to do on each row in each cell-element goes
  % here
end

I already convert it but it should be seperated as per requirements like there are 5 rows so each row include 3 column. If I want to change the data structure from n rows* 15 column. After 3 column, new column will be new raw of the current data sets. Hence you understand the concept of the structure of data but I want to it for millions of data hence it should be in loop and easy to access. Thank you
