csape function alternative for R 2015a

Hello, I have a code which was written in R2011a version. The code has a function csape in a part of the code. However when i run the code in R2014a, it gives an error stating "undefined function csape" Can anyone suggest me an alternate function to csape

The csape function is part of Curve Fitting Toolbox. You likely had this toolbox installed in your older release, but don't have it installed in the release you're using now. You can check if this toolbox is installed using the ver function.
