CAM Matrix Vector Array Samples

mvasamp1.cpp This program sets up a and solves a linear system of equations.
mvasamp2.cpp This program demonstrates file input/output by constructing a matrix and a vector, writing it to a file, and then reading it back in. The program then solves the linear system represented by the matrix and the vector.
mvasamp3.cpp This program demonstrates the use of sub-matrix and sub-vector access,
and index range access, by implementing a naive Gaussian elimination routine and a Gaussian elimination routine with partial pivoting.
