I have this plot that shows the same colors and I would like add points, N=1 would be boxes, N=9 would be triangles, N=20 would be circles. As well as change each of their colors and thickness. Data is showing up in legend and I would want to take that out.
Mat_w = -.5:.5:.5;
u = s\f;
title('Case 2')
legend('N=5','N=9', 'N=20');
hold on
plot(Mat_w, u, 'g-')
xlim([-w,w])

Try:
Mat_w = -.5:.5:.5;
u = s\f;
title('Case 2')
hold on
plot(Mat_w, u)
xlim([-w,w])
legend('N=5','N=9', 'N=20');

That cleared up the data part in the legend, how do I change each color and make them plot different line styles?

What is s and f? It is not defined/ given in the code.
