This is a C++ template form library to perform matrix calculations with relaxation and efficiency in your program. It supports most of the matrix calculations that you may indigence to do in your C++ programs. With this form you tin do matrix calculations barely like other built-in data types in your program. It supports arithmetic operations, sub-matrix operations, inversion, various matrix decompositions, solution of simultaneous linear equations, eigen value and eigen vector problem, and much more. Full source encode is included with the package. This form is optimized for performance and memory usage and incurs negligible programming overhead over "C" programs. But it supports but thick matrices and not the sparse matrices. We get tested matrices of size up to 1000 x 1000 with this form. This package tin be used with any modern ANSI / ISO compliant C++ compilers on any platforms. However, we get tested this package but with the following compilers. Compilers Tested: Borland C++ 5.5 C++ Builder 4.0 and 5.0 MS Visual C++ 5.0, and 6.0 If you want to apply it with a different compiler not listed above, please contact us at matrix@techsoftpl.com.
