interpolate()

Interpolates data

Syntax
y = interpolate(InterpType,Data,iVar1,iVal1,iVar2,iVal2,....,iVarN,iValN)

Arguments

Name	Description	Range	Type	Required
InterpType	Type of interpolation	"linear", "cubic", "spline"	string	yes
Data	Data to interpolate		integer, real	yes
iVar1, iVar2,.	Dimension of independent variable to interpolate		integer	yes
iVal1, iVal2,.	values to interpolate		integer, real	yes

Examples

linI = interpolate("linear", colY, 1,[1::0.5::4])
cubicI = interpolate("cubic", colY, 1,[1::0.2::2])
splineI = interpolate("spline", colY, 1,[-2::0.2::2])
For a 2-D data with 2 independents, the following interpolates dimension 1 (inner-most) from 1 to 4 in steps of 0.5 and second dimension at 0.5:
linI = interpolate("linear", colY, 1,[1::0.5::4],2,0.5)
