How to iterate creating matrices that are not altered by previous results?

Hi guys. Im new using matlab and I´m trying to do a sort of iteration process, from a matrix I have in a excel sheet. I want to put a Nan in every cell one by one and as a result finding the mean of the whole matrix, the code im usin is: for i=1:12; for j=1:26; w(i,j)=NaN w(isnan(w))=0 promannnnn(i,j)=mean(mean(w)) y{i,j} = promannnnn; end end

The previous code kind of do the job but every iteration is being affected by the one done before, and that is not what i want, hope somebody could aid me

thanks

Your code is not clear.. You are making w(i,j) NaN ..and replacing nan's with zeros..you have not initialized w and y.

I am not sure if I understand your questions but using:

mean

you can actually omitnan

A = [1 0 0 1 NaN 1 NaN 0];
M = mean(A,'omitnan')

Does this help you?
