MATLAB: Am I getting this error “Function ‘subsindex’ is not defined for values of class ‘cell’. Error in dp_p2 (line 14) f(n, fmax(2), fmax(3), fmax(4)) = MAX;”

cellsubsindex

q = xlsread('dp2sp.xlsx'); w = [12 10 10]; f = zeros(length(q(:,1)+1), w(1), w(2), w(3));
for n = length(q(1,:)):-1:1
ff = 0; ff =f(n+1, :, :, :); [MAX,I] = max(ff(:)); dims = size(ff); fmax = cell(size(dims)); [fmax{:}] = ind2sub(dims,I);
    f(n, fmax(2), fmax(3), fmax(4)) =  MAX;
    f(n, fmax(2), fmax(3), fmax(4)) = 0;
     for k = 1:prod(w)
     if q(n,1) + fmax(2) <= 12
     if q(n,2) + fmax(3) <= 10
     if q(n,3) + fmax(4) <= 10
     [MAX,I] = maxk(ff(:),k);
     MAX = MAX(k);
     I = I(k);
     dims = size(ff);
     fmax = cell(size(dims));
     [fmax{:}] = ind2sub(dims,I);
     f(n, fmax(2) + q(n,1), fmax(3) + q(n,2), fmax(4) + q(n,3)) = sum(q(n,:)) + MAX;
     a(n, fmax(2) + q(n,1), fmax(3) + q(n,2), fmax(4) + q(n,3)) = 1;
     break
     end
     end
     end
     end
end

Best Answer

 f(n, fmax{2}, fmax{3}, fmax{4} ) = MAX;
