MtrxCal

Don't spent hours writing a program for some programmable calculator while MtrxCal can perform the same calculations with just a few simple lines. Don't waste time trying to find the right maximum and minimum values for plotting your functions. Just let MtrxCal use its build-in auto-scaling feature. The syntax for adding two values and adding two matrices containing hundreds of values is the same. Define a range like x=[-6:0.1:6] and calculate the sinus of this matrix like y=sin(x). Now you can just plot all the values with the command plot(y) or plot the power of y using the command plot(y.^2)

Matrix ActiveX Component

The Matrix ActiveX Component is a useful tool that can simplify the use of matrix operations for mathematical computations in application development. It provides for matrix operations such as addition, subtraction, multiplication, inversion, transpose, and computation of determinant, LU and Cholesky decompositions. Advanced edition additionally supports QR and Singular Value (SVD) decompositions, Eigenvalue and Eigenvector computation for symmetric and non symmetric matrices. Advanced II edition now supports operations with complex matrices. The Matrix ActiveX Component delivers all the speed, numerical stability, robustness and scalability you could ask for, significantly reducing development time and allowing you to focus on the actual goals of your application. Without compromising speed, it uses an object-oriented approach to matrix math computation, it provides you with the Matrix and CMatrix Classes containing all the Properties, Methods that you'll need when deploying your numerical exploration.

You may be developing a statistical package, or you might want fast 3D graphics transformations, or you may need to solve simultaneous equations, multivariate linear regressions, or to solve EigenValues and EigenVectors problems, Matrix ActiveX Component can do all of this and more.

Matrix Inverse Calculator

This program uses the complicated Gauss-Jordan elimination method to find the inverse of any square matrix. You simply choose your matrix's dimensions, and then enter the elements of the matrix you want inverted in the left frame. When you press Enter, the inverse matrix will be shown in the right frame. If your matrix doesn't have an inverse, you will be told so. You can also use the randomize button to fill in your matrix with random elements. This is useful if you don't want to type the elements manually and just want to test the program.

MatrixCalculator

Morello Matrix Calculator is a simple, pocket calculator style program which performs most standard matrix calculations. It supports matrices up to 20 elements square (shareware version is limited to 2 elements square). It also allows data to be exchanged with most common spreadsheets and other programs via the clipboard or text files

Linear Algebra

Performs computations associated with matrices, including solution of linear systems of equations (even least squares solution of over-determined or inconsistent systems and solution by LU factors), matrix operations (add, subtract, multiply), finding the determinant, trace, inverse, adjoint, QR or LU factors, eigenvalues and eigenvectors, establish the definiteness of a symmetric matrix, perform scalar multiplication, transposition, shift, create matrices of zeroes or ones, identity, symmetric, general, random matrices, etc.

MatrixShow ActiveX

Shows the content of matrices, that are given as two-dimensional arrays. This can be done both in runtime mode and in design mode. The element itself is invisible. It shows a form to give out the matrix content. The matrix display for example serves debugging purposes.

Matrix TCL

This is a C++ template class library to perform matrix calculations with ease and efficiency in your program. It supports most of the matrix calculations that you may need to do in your C++ programs. With this class you can do matrix calculations just 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 code is included with the package. This class is optimized for performance and memory usage and incurs negligible programming overhead over "C" programs. But it supports only dense matrices and not the sparse matrices. We have tested matrices of size up to 1000 x 1000 with this class. This package can be used with any modern ANSI/ISO compliant C++ compilers on any platforms. However, we have tested this package only 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 use it with a different compiler not listed above, please contact us at matrix@techsoftpl.com.
