   Result=cellfun(@(IDX) min(M(IDX)), index, 'uniform', 0); < error occurs on this line finding minimum of M at z=1, how do i fix this?

Is it because of the zeros in index?

[Joseph Lee]

cellfun(@(m, IDX) min(m(IDX)), M, index, 'uniform', 0)

Tried this code but got another error: Subscripted assignment dimension mismatch.

Result = zeros(size(index));
t = ~cellfun(@isempty,index);
Result(t) = cellfun(@(mm,ii)min(mm(ii)),M(t),index(t));

[Joseph Lee]

I got the same error:Subscripted assignment dimension mismatch.

I think i know why, the minimum im looking for is not for each cell array but for all the cells, the result should give only one single value which i am storing into a matrix while increasing the find(abs(Z-1)<0.005) to find(abs(Z-2)<0.005) and so on

Do i just add min?

Result(t) = min(cellfun(@(mm,ii)min(mm(ii)),M(t),index(t)));

[Joseph Lee]

This does not seem to work. I will open another question to be more specific
