SOLVE for Function Vectors

[NomadVehr]

Thanks a lot Road!

Tried it out and works like a charm.
Here´s the code
I used X since I copied the equations from the 2 variable statistics app.

EXPORT PUMP1(X)
BEGIN
LOCAL h;
h:=2.89237307957ᴇ−8*X^4-2.24570549144ᴇ−5*X^3+4.67273696234ᴇ−3*X^2-0.311626877884*X+175;
LOCAL Eff;
Eff:=8.58164056499ᴇ−8*X^3-1.00216261706ᴇ−3*X^2+0.480844232375*X-0.029541916438;
LOCAL PWR;
PWR:=0.25415412597*X+68.328377716;
return {"h(m)",h,"Eff(%)",Eff,"SHP(kW)",PWR};
END;
