PURPOSE

Projection Pursuit function for dePDDP algorithm

SYNOPSIS

function [v, fval, idx] = depddppp(X, pars)

DESCRIPTION

Projection Pursuit function for dePDDP algorithm
[V, FVAL, IDX] = DEPDDPPP(X, PARS)

 Inputs:
    (X): N-by-D data matrix
    (PARS): Parameter structure containing algorithm parameters

 Output:
    (V): Projection vector: 1st Principal Component of X
    (FVAL): Function of KDE at split point
    (IDX): Binary cluster assignment
