findx: Find intersects of quadratics

In phewson/PhilsAngle: Helps identify lens angles

Description

Uses Matthew's work to find the points where the two quadratic curves intersect

Usage

findx(a, b, k)

Arguments

a
b
k

Examples

##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,
##--	or do  help(data=index)  for the standard data sets.

## The function is currently defined as
function (a, b, k) 
{
    x <- ((b[2] - a[2]) + k * (sqrt((a[2] - b[2])^2 - (4 * (a[3] - 
        b[3])) * (a[1] - b[1]))))/(2 * (a[3] - b[3]))
    return(x)
  }
