Interpolation functions

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
c	5	0	-2
