Use of sequential feature selection

I am trying to use the sequential features selection algorithms using "sequentialfs" command. I want to use the "Keep in" options so that some features have to be included by default. Can someone tell me how to use it?

I would try

'KeepIn',[true false false true]

in the function call to keep in the first and fourth of four features.
