Error using sortrows in my optimisation script after for loop

Error using matlab.internal.math.sortrowsParseInputs Column sorting vector must contain integers with absolute value between 1 and the number of columns in the first argument. Error in sortrows (line 64) [col, nanflag, compareflag] = matlab.internal.math.sortrowsParseInputs(ismatrix(A),size(A,2),A,varargin{:}); Error in TLP (line 110) sol_sorted = sortrows(sol,17);

Before calling "sortrows", check whether "sol" is really a matrix or table of class "double" that has at least 17 columns.

Hi Torsten,

Thank you, but checked sol which has 8 column, but I still have the same error

% Dt = 4*((Fb/(4*rho_Water))-(Width - 2*Dc)*Hp)/(pi*Dc.^2);

if (GM>MetaC)%&& Dc < Cs && Dc>lpt && Dt>Hp && Hc>Dt

% data_feasible=[data_feasible; Dc, Hc, Hp, Mt, Dtd, DeckH, Dt];

W = MassT + Mt + 4*(Vc1+Vc2)*rhoCL + 4*Vn*rhoNd + 4*Vp*rhoPT + Nm*Vtd*rhoTD ;

% TMass = MassT + Mt + 4*(Vc1+Vc2)*rhoCL + 4*Vn*rhoNd + 4*Vp*rhoPT + Nm*Vtd*rhoTD ;

sol=[sol; Dt, DeckH, Dtd, Mt, Hp, Hc, Dc, W]; %#ok<AGROW> % Store the feasible solution

end

end

end

end

end

end

end

end

% sort the matrix of feasible solutions based on the objective (here vol, the third column)

sol_sorted = sortrows(sol,8);

% Select the first solution (which is the optimum after sorting all solutions based on the objective)

opt_sol=sol_sorted(1,:);

Before calling "sortrows", insert the two lines of code

size(sol)
class(sol)

and tell us what MATLAB prints to console.
