subscript for loop finding max value index

Hi Im trying to use a find function on the for loop, but Im getting an error that. In an assignment A(I) = B, the number of elements in B and I must be the same. This is the line im trying to fix. I need to add (n) to right side of the equation, but I don't know where to place it.

for n=1:13

indm(n) = (find(longm == max(longm((dataind{n})))))

end

dataind is an array of indices used in a calculation

Ultimately what Im trying to do is to find the indices of the maximum values of a vector length (1x30000) in a for loop, i should get a result of a vector of length 1x13

Thanks
