matrices (2 products)

Linear Algebra 2 (Shareware, $15)

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.

Matrix Inverse Calculator 1.0 (Freeware)

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.
