MatrixC++ - README

MatrixC++ is a lightweight matrix library developed in C++. MatrixC++ is designed
to help solve engineering and math problems requiring vectors and matrices.
MatrixC++ is OS independent and is as portable as we can make it. MatrixC++
supports overloaded operators, links with Lapack, and includes functions to
facilitate porting from Octave type matrix scripting languages to C++.

Platforms

MatrixC++ compiles and runs with g++, clang++, and Visual Studio 2015.

Simple Example:

#include <iostream>
#include "matrixCPlusPlus.h"

int main(void) {

    matrixCPlusPlus::Matrix<double,3,3> A = {1.,2.,3.,0.,0.,0.,0,0,0};
    matrixCPlusPlus::Matrix<double,3,3> B = {1,1,1,3,4,5,3,6,10};
    std::cout << A+inv(B);

    return(0);
}

To compile: $ g++ example.cpp -llapack or
g++ example.cpp "-l:liblapack.so.3"

See also matrixCPlusPlus.cpp for an additional ideas.

Installation

Place matrixCPlusPlus.h in the directory of your choosing. Tell your
compiler where it is. For g++, add -I<your directory="">; see the provided
Makefile for an example. In your code, #include "matrixCPlusPlus.h" where you
need to and off you go.</your>

Dependencies

If one needs to take a matrix inverse or determinant, Lapack
is required. Lapack is an open source linear algebra package and is available
from http://www.netlib.org/lapack/. For Linux, Cygwin and MinGW users, one can
install or build Lapack very easily. Visual Studio platforms can require a bit
more effort. Most expediently, one can download the compiled libraries from
http://icl.cs.utk.edu/lapack-for-windows/lapack/. Another option is compile and
link with CLapack, and f2c'd version of Lapack. In fact, one can extract the
necessary files in less than two hours. In future versions, I plan to include
the requisite files. I also plan to investigate the now included C interface
to Lapack.

suggestions and bug fixes.
