How can i size my array to the output of a nested for loop? Thanks for the help!
DataArray = nan(300,1); % this is the array that i need to make sure is big enough to take in the data....
inputValsY3 = -20:20;
for y = 1:300
for y1 = 1:50
for y2 = 50:100
for y3 = 1:numel(inputValsY3)
[~,~,DataArray(y,y1,y2,y3)] = Function(Close,y,y1,y1,y2,y3);
end
end
end
end

To keep the indexing the same, just use the top value from the loops. E.g.,
DataArray = nan(300,50,100,numel(inputValsY3));
Note that since your for-loop fills in the 3rd index starting at 50, there will be some NaN values left in the array after the loops are done. If you don't want that then you would have to shift the 3rd index down.
