In inflection: Finds the Inflection Point of a Curve

Linear function defined from two planar points (x1,y1) and (x2,y2)

Description

It gives the value of the linear function defined from two points (x1,y1) and (x2,y2) at any x

Usage

lin2(x1, y1, x2, y2, x)

Arguments

x1	the x - abscissa of the first point
y1	the y - ordinate of the first point
x2	the x - abscissa of the second point
y2	the y - ordinate of the second point
x	the x - point where we compute the value of the linear function

Value

It returns the value of the linear function from (x1,y1) to (x2,y2) at an arbitrary x.

Note

The value of a linear function is built by this way for R to be faster than a two-vectors call.
