Spot the outlier - MATLAB Cody - MATLAB Central

Problem 661. Spot the outlier

Difficulty:Rate
All points except for one lie on a line. Which one is the outlier?
Example:
You are given a list of x-y pairs in a column like this:
pts = [ 0 1
0 2
3 2
0 3
0 4 ]
You would return the number 3, since the third point is the only one that is non-collinear with the other points. All the others are on the y-axis.
outlier = 3
