Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.
Try this. locations=[center(1)-offsetx-(.5*boxsize), center(y)-offsety-(.5*boxsize),center(1)-offsetx+(.5*boxsize), center(y)...

I want to split 4D single data (3600*40*40*40) where 3600 is time. I want to split the data for every 36 seconds to get 100 profile containing 36 sec in each profile.
Just put it in a cell array: A = rand(3600,4,4,4); % test array B = mat2cell(A,repmat(36,1,100),4,4,4)
