sw_uniquetol

Syntax

[Mu, firstIdx] = sw_uniquetol(M,tol)

Description

[Mu, firstIdx] = sw_uniquetol(m,tol) returns unique column vectors within the given tol tolerance. Two column vectors are considered unequal, if the distance between them is larger than the tolerance ($\delta$):

$$\sqrt{\sum_i (V_i-U_i)^2} < \delta$$

Input Arguments

M

Matrix that contains column vectors.

tol

Distance tolerance, default value is $10^{-5}$.

Output Arguments

Mu

Matrix that contains the unique column vectors.

firstIdx

Indices pointing to the first occurence of the unique element.

This function is similar to the Matlab built-in unique(M,'rows','first'), but with controllable tolerance.
