i want to know that how can i find the green line graph values at equidistance at x axis interval (0-5) ,i want to know the exact values of x and y coordinates at a particular intervals and at equidistance ie -like this when x is 0 then y value is 0.35,then again same like this how could i find the x and y values of graph,i have to evaluate the points at equidistance .

Hi Prateek,
You can use interp1 function to know the y values for the corresponding x values. You may also refer to follwing example taken from the documentaion of interp1 function.
x = 0:pi/4:2*pi;
v = sin(x);
xq = 0:pi/16:2*pi;
figure
vq1 = interp1(x,v,xq);
plot(x,v,'o',xq,vq1,':.');
xlim([0 2*pi]);
title('(Default) Linear Interpolation');
