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};

Thanks Walter. Yes, Y(m) = c + V{m} worked. The simple, straight forward answers are often the best, as was proven in this case.

How are you storing the entire array in Y(m) ? Is c symbolic, or is V{m} symbolic?
