Hi guys! I've plotted the red curve through a set of data (.txt file of points):

How can I extend the red curve untile axes of cartesian plane ?

It doesnt seem to happen with interpolation(interp1)...atleast for me. But i've come up with an alternative based on the geometry and i've explained the reason along the code. Hope this helpsuntitled.jpg

It's basically the same concept for the other end. You just have to copy paste and change the values. But this is not an accurate result, mind you

Hi,
You can use interp1 function to interpolate your plot till x=0. There are different methods the function adopts for interpolation. You can choose from these methods to achieve appropriate interpolation. For more details on interp1 go through the link below.
