create an new cell array everytime a loop cycles through in matlab

Question

I am new to MatLab but I have some experience with C#. I have a large dataset <169360x97> that I need to break up into 464 cell arrays. I currently have a loop that will cycle through the dataset and make a cell array, but I can not figure out how to have the loop create a new cell array every time instead of just rewriting over the same data. Here is the loop I have written.

    b=5476;
    e=5840;
    while(b<169360)
     dataset2cell(JeaAddressKwh(b:e,1:97));
     b=e+1;
     e=e+365;
    end

I have tried the following, but i get an error message every time:

   n=16;
   b=5476;
   e=5840;
   while(b<169360)
    n=dataset2cell(JeaAddressKwh(b:e,1:97));
    n+1;
    b=e+1;
    e=e+365;
   end

So basically what I am trying to get as an output is a different cell array called 16 through 464. I would appreciate any help. Thanks.

In the first loop you are not saving the cell array and in the second loop you over overwriting the previous cell array and trying to add 1 to it, without saving the result.

Try something like this:

   n=cell(16,1);
   b=5476;
   e=5840;
   i = 1;
   while(b<169360)
       n{i}=dataset2cell(JeaAddressKwh(b:e,1:97));
       i = i+1;
       b=e+1;
       e=e+365;
   end
