Excel Extra Functions - interpolate, cubic spline, polynomial curve fitting, and etc.

[losmoscas]

Hi guys.

I´m looking for extra functions for three dimensional interpolate and extrapolate functions; two dimensional interpolate, extrapolate, cubic spline, polynomial curve fitting, line intersections, minima, maxima, first derivative, and second derivative for Microsoft Excel 2007 on Windows7 x64bits.

I tried using XlXtrFun, but don´t run on excel 2007 and 2003 with windows7 x64bits.

if someone have a spreadsheet that works, plz upload!

Thanks!
