How can I store a matrix within another matrix?

70 views (last 30 days)
I have a set of data that is 315x3 Double that I need to store as 1x3 double in an array of size 3x5x21. I need it in this form so I can manipulate it in simulink using a lookup table.
What would be a way to do this?

You could try something like:
reshape(dat, [3,5,21,3])

%create a cell array
c = cell(1,3); % cell array can contain anything
c{1} = data(3,5,21);
c{2} = data(3,5,21);
c{3} = data(3,5,21);
