returns the difference between 2 4x4 HT matrices

Description

p checks the distance of the origins
z checks the distance angle of the ez vectors
y checks the distance angle of the ey vectors
l checks the straight line distance angle of ez

Syntax

[T,ia,ic]=uniqueT(T,[check,thr])

Input Parameter

T: list of HT Matrix A
check: letters of distances to check default is 'pz'
thr: default 1e-4;

Property names

'last' : if 'last, not the first but the last T is used

Output Parameter

T: logical true
ia: index a
ic: index c
