??? Undefined function or method 'plus' for input arguments of type 'cell'.??

Dear all,

I created a model ARMA with Kohonen, but I have an error while predicting time series in line:

wynikz(ii,1) = wynik(length(wynik)) + first; 
??? Undefined function or method 'plus' for input arguments of type 'cell'.???

I modified the line on:

wynikz(ii,1) = cellfun(@plus,wynik(length(wynik)),mat2cell(first),'UniformOutput',false);

but MATLAB said that solve() is obsolete. I don't know how to solve the problem :( Thanks you for answer.

Either wynik or first must be a cell. MATLAB does not know how to add cells together. Why not? See the FAQ: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F

You can use {} to get the contents of the cell. So maybe you want:

wynikz{ii,1} = wynik{end, 1} + first{1};

or something like that - it really depends on the data types of wynikz and first, so the syntax might be slightly different depending on exactly what they are.
