I have a problem when running my code. For some reason , my plotting doesn't work, thus my graph is complete blank when I run the code. Please kindly help me to check it. This is script using loop with quad

My function:

function [ g ] = myfun( w,u )

g=1./(9.*(w.^n)-8.*w);

end

My script:

u=[4:1:10];

for iu=1:length(u)

    h=quad(@(w)myfunc(w,n(iu)),6,10);
    v=h(:,1)
    plot(u,v)

end

Thank in advance

在 MATLAB Online 中打开

Try this:

myfunc = @(w,n) 1./(9.*(w.^n)-8.*w);
u=[4:1:10];
n = some vector;
for iu=1:length(u)
        v(iu) = quad(@(w)myfunc(w,n(iu)),6,10);
end
figure(1)
plot(u, v)
