Margin of *k*-nearest neighbor classifier

returns the classification margins for
`m`

= margin(`mdl`

,`tbl`

,`ResponseVarName`

)`mdl`

with data `tbl`

and classification
`tbl.ResponseVarName`

. If `tbl`

contains the
response variable used to train `mdl`

, then you do not need to
specify `ResponseVarName`

.

`m`

is returned as a numeric vector of length
`size(tbl,1)`

. Each entry in `m`

represents
the margin for the corresponding row of `tbl`

and the
corresponding true class label in `tbl.ResponseVarName`

, computed
using `mdl`

.
