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`

, computed
