Hi, I am new to Matlab programming. The graph result should be have a range of x-asix from -1 to 1, but now the graph is from 0 to 1. I want to set the range for x-axis from -1 to 1. May I know anyone can help me?
This is the current program code.

Here is my best guess at what you should do, to get what you want:
- Take the x argument out of the call to interp1
- Change the definition of interp_no_ding to be interp_no_ding = -1:1/50:1
