Isotropic Cartesian Matching
matcher=1d values*='<x>' params='<error>'
matcher=2d values*='<x> <y>' params='<error>'
The 1d
matcher compares positions in 1-dimensional
Cartesian space.
Rows are considered to match if their x
column
values differ by no more than error
.
The 2d
matcher compares postions in 2-dimensional
Cartesian space.
Rows are considered to match if the difference in their
(x
,y
) positions reckoned using
Pythagoras is less than error
.
Matching in any number of Cartesian dimensions can be done by extending this syntax in the obvious way.
