PURPOSE

Projection Pursuit function for PDDP algorithm

SYNOPSIS

function [v, fval, idx] = pddppp(Data, pars)

DESCRIPTION

Projection Pursuit function for PDDP algorithm
[V, FVAL, IDX] = PDDPPP(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): Total scatter of (X)
    (IDX): Binary cluster assignment
