error in running loop : the resultant is giving an empty array

here is complete code.can anybody please check this

problem is in the last loop of total{k,j}.when I run the code the counts should be 14794752 since k=115584 and j=128 but after running code the counts are only 128 and resultant is all 0x0 double in <115584x128>cell.. please some body copy paste this n check if their systems are also giving this ? a file used in this code is also given here

summyia - I think that the problem is with the line

 for k=numel(Time_of_machine_inCells)

k is being initialized to a single value and so you are not iterating over anything. You probably want to use

 for k=1:numel(Time_of_machine_inCells)

instead. Note that this will take a lot (!) longer to run. :)

yes or sure..but I have no other way to shorten this code and thanks you were right.what if it says not enough memory?what should I do?
