I have a cell array where the cells are something like this: [ 92x1 double] [215x1 double] [127x1 double] [120x1 double] [ 89x1 double] ....and so on(1000 odd cells). I want to find the means of the negative and positive elements in these cells individually. I tried :
if true
% code
end
m = (s{i})<0;
m1 =cellfun(@(x) [mean(mean(x(m,:),2))],s,'un',0)
but when I try the same for all positive elements using n = (s{i})>0; it says index exceeds matrix dimension. Any idea of what I may be doing wrong and how I can fix this or any other suggestions? Thanks!
