How can I do a convex smoothing to a set of points in Matlab?

Hi
I'm using the function spline to do a cubic spline interpolation, nevertheless given the nature of that functions some parts are not convex. I need to ensure the convexity of the smoothed function, is there a way to do something similar like the spline but keeping it convex?
Many Thanks

This FEX file let's you constrain a spline fit to be convex

Well then it wouldn't go through the knots. It would be a regression rather than an interpolation. Or do some kinds of splines not need to go through the knots?

Yes, it would be a regression, but I assume that's what the OP wants, as the title of the post mentions "convex smoothing".
