 What mistake am I making here?
clc
x0 = [0.01, 1, 10 + 273.15, 8, 1];
options = optimset('PlotFcns',@optimplotfval);
fitnessfcn = @(x)Lobo(x(1), x(2), x(3), x(4), x(5));
[X, fval] = gamultiobj(fitnessfcn, 5, [], [], [], [], [], [], options);
X
disp(X);
d0 = 0.01:10;
Qr{:,1} = @(x)Lobo(x(1), x(2), x(3), x(4), x(5));
plot (d0,Qr{:,1});
xlabel('(d0)');
ylabel('flux (qr)');

@Devdatt Thengdi: call that function! If the function has been written using vectorized code then simply call it with a vector of the independent variable values. If the function is not vectorized use a loop or arrayfun.

You might like to try using ezplot first.
