Can LabVIEW perform a 4th-order spline interpolation or am I doomed to derive it myself? I need a 4th-order spline because I must verify that my first, second, and third derivatives are continuous. I especially can not afford to have my third derivative to possibly be discontinuous.
LabVIEW does have some spline functions under Mathematics » Interpolation & Extrapolation if you have above the Base package (FDS or PDS). If not, you can always search for example code but you might just have to derive it.
