cell matrix: code does not work.. can somebody help?

i got a load of data and wanted to seperate it and store it into a cell array

frames = [680, 4280, 4940, 8380, 9140, 12460, 13220, 16980, 17780, 21400;
        860, 4100, 4420, 7700, 8340, 11760, 12420, 15760, 16740 ,20060;
        1180, 4240, 4980, 8020, 8520, 11780, 12660, 16140, 17040, 20020;
        980, 4100, 4820, 7940, 8640, 11920, 12780, 15880, 16840, 20160];
zyklen = cell(length(frames(1,:))/2,length(frames(:,1)),2); %5...WH, 4...Sätze, 2...vm/s
for i = 1:length(zyklen(:,1,1))
  for l = 1:2
      for j = 1:length(zyklen(1,:,1))
          for k = 1:2
              if(j<length(zyklen(1,1,:))-1)
                  zyklen{i,j,k} = num2cell(a(frames(l,j):frames(l,j+1), k));
                  zyklen{i,j,k} = num2cell(b(frames(l+2,j):frames(l,j+1), k));
                  zyklen{i,j,k} = num2cell(c(frames(l+4,j):frames(l,j+1), k));
                  zyklen{i,j,k} = num2cell(d(frames(l+6,j):frames(l,j+1), k));
              else
                  zyklen{i,j,k} = num2cell(a(frames(l,j):frames(l,j), k));
                  zyklen{i,j,k} = num2cell(b(frames(l,j):frames(l,j), k));
                  zyklen{i,j,k} = num2cell(c(frames(l,j):frames(l,j), k));
                  zyklen{i,j,k} = num2cell(d(frames(l,j):frames(l,j), k));
              end
          end
      end
  end
end

in frames are the beginning and endvalues of a EMG, i just want to store them in cells to get them compact in one place. but it seems not to work, as if my matrices (a,b,c,d) are about 22000x2 and every cell only gets 1 value.

 cellplot(zyklen(1,1,1));

there should be some thousand values

Try to replace

zyklen{i,j,k} = num2cell(a(frames(l,j):frames(l,j+1), k));

by

zyklen{i,j,k} = a(frames(l,j):frames(l,j+1), k);

This is a bad idea:

if(j<length(zyklen(1,1,:))-1)

Prefer:

if j < size(zyklen, 3) - 1

because it does not waste time with creating zyklen(1,1,:) only to measure its length.
