Re: seeking quadratic interpolation in Matlab?

Does anybody have quadratic interpolation in Matlab? I searched for it in
Matlab built-in functions, surprisingly Matlab doesn't provide a quadratic
interpolation function.

Why do you want a (specifically) piecewise quadratic
interpolation?

Why not use a cubic spline? Its a better choice in
general anyway. And you have a choice of a standard
spline, or of a pchip interpolant in matlab, either
without need of the splines toolbox.

If you insist on a quadratic interpolant, then look at
spapi from the splines toolbox.
