Description: Introduction
=== ===
This a class for symmetric matrix related computations. It can be used for
symmetric matrix diagonalization and inversion. If given the covariance matrix,
users can utilize the class for principal component analysis(PCA) and fisher
discriminant analysis(FDA). It can also be used for some elementary matrix and
vector computations.
Usage
=====
It s a C++ program for symmetric matrix diagonalization, inversion and principal
component anlaysis(PCA).
To use it, you need to define an instance of CMatrix class, initialize matrix,
call the public funtions, and finally, free the matrix. For example, for PCA,
CMarix theMat // define CMatrix instance
float** C // define n*n matrix
C = theMat.allocMat( n )
Calculate the matrix (e.g., covariance matrix from data)
float*phi,*lambda // eigenvectors and eigenvalues
int vecNum // number of eigenvectors (<=n)
phi = new float [n*vecNum]
lambda = new float [vecNum]
