Inverse Software

A collection of Animated Inverse Cursors for Windows 95/98/ME/NT/2000. Each cursor is the opposite color of the portion of the computer screen it is held over, just move the cursor and it changes! They replace the standard Windows mouse pointers with animated versions. There are 39 cursors in the set. The cursors are copyrighted but free for personal use.

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.

This is a programmable multiple-precision hex calculator with many utilities. With Hpmbcalc, you can easily perform a lot of big number math and encryption operations, such as: square root, modular inverse; hash, CRC, and check sum make; shift register configuration evaluation and simulationl; pseudo-random number generation; primality test; hex, dec, oct, bin conversion; etc.

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