is_in.p(x=0.5,p=matrix(c(0,1),ncol=1))
is_in.p(x=matrix(-.5,ncol=2,nrow=1),p=matrix(c(0,0,1,1,0,0),ncol=2))
is_in.p(x=matrix(.25,ncol=2,nrow=1),p=matrix(c(0,0,1,1,0,0),ncol=2))
is_in.p(x=matrix(-.5,ncol=3,nrow=1),p=matrix(c(0,0,0,1,0,0,0,1,0,0,0,1),ncol=3,byrow = TRUE))
is_in.p(x=matrix(.25,ncol=3,nrow=1),p=matrix(c(0,0,0,1,0,0,0,1,0,0,0,1),ncol=3,byrow = TRUE))
