Save in a cell array from a loop

For every iterration of my loop I have a 2D matrix (A), but the number of rows is different every time.

Ideally, in the end Iwould like to have a 3D matrix [(A)which is 2D x number of iterrations]. As I can't save in matrix format,

how can I save the results in a cell array? and how can I access the data fro a specific itteration?

ndays=365;

for d=1:ndays
help=[Temperature(:,d),Idx(:,d)];
idx=Idx(:,d);
tst=find(idx==6);
take=help(tst,:);
%save test in a 3D matrix [takex ndays];
end

Do you want to save take? Or maybe tst? Either way, you can create a cell array

C = cell(ndays,1);

before the loop and store whatever you want in C{d} at each iteration of the loop.

For example:

ndays=365;
C = cell(ndays,1);
for d=1:ndays
help=[Temperature(:,d),Idx(:,d)];
idx=Idx(:,d);
tst=find(idx==6);
take=help(tst,:);
%save test in a 3D matrix [takex ndays];
C{d} = take;
end

To access the data, you use the same syntax used to store the data. To get the data from the 5th iteration, for example, you can use

data = C{5}

However, running your code on the .mat files you provided gave me an error after 10 iterations because Temperature and Idx only have 10 columns instead of 365 columns.

Yes, because it was to big to upload it all:) Thank you for your help:)

Ah that makes sense - happy to help!
