% name: MaxEff.m function [MaxEff] = KTKQMaxEffoutput(OptEff)
MaxEff = zeros(size(OptEff, 2), size(OptEff, 3)); for im = 1:size(OptEff, 2) for iim = 1:size(OptEff, 3) MaxEff(im, iim) = findpeaks(OptEff(:, im,iim)); end end %MaxEffAVE = zeros(MaxEff, 1); %for ia = 1:size(MaxEff, 2) % MaxEffAVE(ia) = findpeaks(MaxEff(:, ia)); %end
end
that is my code and the OptEff is 17x10x11 and i want to get the peaks out!
Please help me.

Do you see that omitting the code formatting decreases the readability of your code?

Hi Jonathan,
Your problem is that the findpeaks function can return an empty array, [ ], or an array with multiple entries [peak1, peak2, ..., peakN], neither of which can be assigned to a single array element.
My suggestion would be to make your MaxEff variable a cell rather than an array. Declare MaxEff like this:
MaxEff = cell(size(OptEff, 2), size(OptEff, 3));
and access it like this:
MaxEff{im, iim} = findpeaks(OptEff(:, im,iim));
Hope that helps,
Elliot
