Hi everyone~
I did some curve fitting using curve fitting toolbox. But I don't know how to get the fitting curve. Can somebody help?

Also, in the future I want to do this using code. I'm reading the manual for spline fitting. http://www.mathworks.com/help/curvefit/construction.html
There seems to be lots of kinds of it. I want it shape-conserve, and must pass all the points. Which one should I use?
Any help is appreciated. Thank you!

Use pchip to create a shape preserving spline. ppval can evaluate it.
