MATLAB: Determine the Y value from a given X from the generated figure

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)

Just use the exact same code as for the first figure:

 xlabel('Distance(mm)');     % remove xlabel1 =
 ylabel('Delta(0kg)');       % remove ylabel1 =
 figure_FontSize = 12;
 set(get(gca,'XLabel'),'FontSize',figure_FontSize,'Vertical','top');
 set(get(gca,'YLabel'),'FontSize',figure_FontSize,'Vertical','middle');

MATLAB: I have two array x=[1 6 8 9],y=[3 6 9 14],then i plot (x,y) in matlab. i have no linear equation of x,y. i have only above array of x and y. if value of x is 4 then what is the value of y.

x=[1 6 8 9]
y=[3 6 9 14]
x0=4
y0=interp1(x,y,x0)
