 I am a Matlab beginner and I need to estimate the term structure of
interest rate susing Nelson and Siegel 1987 approach.
I am wondering if someone has a reference or an file for the topic because
I don't know how to start or how to proceed.
Any kind of help would be greatly appreciated
Best regards
