Good afternoon. I have the following problem I have a matrix (XonT) that is variable in size and "double", and I am trying to add a row of type "char" to the end of the XonT matrix, but I can not understand it. , and I guess it's due to the Incopatibility between types. Is there any way to achieve this? I leave the following code in which I am working. Thank you.
Modos = (TTT(1:NP,1:NP)*(10^6)*Cant_port) - ((sol_frec(f,1))^2)*Matriz_masa ;
EO1= Modos(2:NP, 1);
EOO= Modos(2:NP, 2:NP);
Xon = inv(EOO)*(-1)*(EO1);
XonT (:, f) = Xon;
XonT (NP+1, f)= ['Mod',num2str(f)] ;
