I am doing a cubic spline interpolation with some data points. I want the slope at the left end to be zero and don't do anything to the slope at the right end(In the online example, both slope at both ends are forced to be zero). Does anyone know how to do this? Thank you.
Here is my data points:
x = [0,0.152789493879,0.305539702586,0.458371723707,...
y = [0,0.013083199999528,0.155041100006201,0.209241100004874,...
