file	AlgGamma.c
	Functions for computing gamma and incomplete gamma functions.
file	AlgGrayCode.c
	Provides functions for computing Gray codes and their inverse. See Christopher H. Hamilton. "Range Searching Data Structures with Cache Locality" PhD Thesis, Dalhousie University, March 20011. The code within this file is derived from this thesis and the software it refers to.
file	AlgHeapSort.c
	General purpose heap sort algorithms.
file	AlgHilbertIndex.c
	Provides functions for Hilbert indices and their inverse. See J. K. Lawder "Calculation of Mappings Between One an n-dimensional Values Using the Hilbert Space-filling Curve", Birkbeck, University of London Research Report BBKCS-00-01, 2000. The code in this technical report has been modifiied to support n-dimensions and variable bit orders without recompilation.
file	AlgLinearFit.c
	Provides functions for fitting linear models to data, ie linear regression.
file	AlgMatrix.c
	Matrix allocation and maintenance functions.
file	AlgMatrixCG.c
	Conjugate Gradient iterative method with preconditioning for the solution of linear systems with the form \(\mathbf{A} \mathbf{x} = \mathbf{b}\). A must be a symmetric postive definite matrix, i.e. \({\mathbf{x}}^T \mathbf{A} \mathbf{x} < 0\), \(\forall \mathbf{x} \not= \mathbf{0}\), \(\mathbf{x} \in R^n\).
file	AlgMatrixGauss.c
	Provides a function for solving matrix equations of the form: A.x = b for x using Gaussian elimination with partial pivoting.
file	AlgMatrixLSQR.c
	Provides functions for solving matrix equations using LSQR. This software is based on lsqr.c, a C version of LSQR derived by James W. Howse jhows.nosp@m.e@la.nosp@m.nl.go.nosp@m.v from the Fortran 77 implementation of C. C. Paige and M. A. Saunders. In most cases the extensive comments from Howse's lsqr.c have been preserved with little change.
