I've saved a 20,000 [3 10] sets of matrixes, called V{count}, while going through a loop of 20,000 iterations and need to recall these in order for a second loop, with a counter m.

How can I recall these in the second loop as I get the error, "Cell contents assignment to a non-cell array object" when coding the following below:

for m = 1 : 1493
    X{m}=V{1:count}; % let X = V so when during loop 1 or 2 or 3 (m=1 or 2 or 3), 
                     % the 1st then 2nd then 3rd V matrix is applied to the Y function below
    Y(m)=c+X(m);
end

What is count?

V{1:count} creates a comma separated list of the first count entries in V, and each time through the loop you assign all count of them to X. Why are you not using

Y(m) = c + V{m};

?

But what size of output are you expecting? Each V{m} is 3 x 10, so presumably c + V{m} would be 3 x 10 as well. You are trying to store that entire matrix into a single element of Y. You would need to use

Y{m} = c + V{m};

or you would need to use

Y(:,:,m) = c + V{m};
