java.lang.ObjectJampack.Zludpp
public class Zludpp
Zludpp implements the LU decomposition with partial pivoting. Specifically, given a matrix A, there is a permunation matrix P, a unit lower triangular matrix L whose subdiagonal elements are less than one in magnitude and a upper triangular matrix U such that
A = PLUZludpp represents P as a pivot array (see Pivot.java ), L as a Zltmat, and U as a Zutmat.
