performance_res(ii,1)=paperoni_o_pezzenti;

adf(ii,1)=results.adf;
correlation(ii,1)=ccor;
sharpe_res(ii,1)=sharpe;
sharpe_k(ii,1)=ksharpe;
performance_k(ii,1)=paperoni_o_pezzentik;
mcoint(ii,1)=m_coint;
end
Matlab give me the following error:
Input A of class cell and input B of class cell must be cell arrays of strings, unless one is a string.

Hi f is a cell array, in where in the first row ther's string elements, and in the other row number.

couples is a matrix nx2 in which for each row ther's two strings, for example
n_1 N_2
n_3 n_4
and so on

Like Geoff and the error message says, it's probably got something else in the cells than only strings. Please read the FAQ first, and then fix your code: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F
Also, I don't know what's going on in this code, despite an abundance of comments, but I bet a table would be a better and easier choice than a cell array.
