df_md

PURPOSE

Derivative of penalised density on hyperplane criterion

SYNOPSIS

function out = df_md(v,X,pars,bmin)

DESCRIPTION

Derivative of penalised density on hyperplane criterion
OUT = DF_MD(V,X,PARS,BMIN)

 Inputs:
    (V): projection vector
    (X): N-by-D Data matrix

    (BMIN): (optional argument) location of optimal split on (v)

 Output:
    (OUT): derivative of penalised density on hyperplane criterion
