Hi,

May I know how to determine the Y value from a given X from the generated figure? As I do not have any y equation.

attached is the matlab file.

Thanks a lot!

If you have your two vectors x and y

y0=interp1(x,y,x0)

This is your plot

figure
x=[0:(D*1000)/760:(D*1000)]
y=delta(80:840,620);
plot(x,y); %plot line y 620

If you want y0 corresponding to x0=D/2

x0=D/2
y0=interp1(x,y,x0)
