Analytica User GuideMore Array FunctionsInterpolation functions

These three functions interpolate across arrays. Given arrays y and x with a common index i, these functions interpolate a value for y corresponding to value v along the x axis.

LinearInterp() and CubicInterp() use these variables:

Index_a:

a b c

Index_b:

1 2 3

Array_a:

Index_b
Index_a: 1 2 3
a 7 -3 1
b -4 -1 6
