Hi Folks,

I have nu_1= 18*9*6 matrix where each page has the same numeric value, ie page 1 all elements =25, page 2 all elements =50 etc.

I am trying to call in each page in a for loop using

    for ii=1:size(nu_1,3)
             i = nu_1(1,1,ii);
                 Calcs(ii)= Z.*i...etc
    end

where z is an 18*9 matrix and i appears to be a 1*1.

How do I modify i such that it becomes an 18*9 matrix (and updates for each ii) because currently i get the error as outlined in the subject header.

Thanks in advanced B

nu_1(:,:,ii)

but note that the result of the right hand side of Calcs would be an 18x9 matrix, and you are trying to store that entire matrix into the single location Calcs(ii). This is the same basic error you are getting with your existing code.

Do I change

Calcs(ii) to Calcs{ii}

Thanks B
