Yesterday, I was searching for some nice mathematics applications, mainly for computer algebra, in Linux and here are my two main conclusions. First, there are hundreds of math programs and libraries out there for any need! Second, try to stick with Debian-based distros, or else you ‘ll end up compiling the universe. In the beginning, [...]
This is a very simple Pascal program I wrote in mid 1990s, which solves a sparse NxN linear system using the Succesive Overrelaxation Method (SOR), which in turn is based on Gauss Seidel Method. Both methods are iterative. N is initially set at maximum …64. You need the W factor for the SOR to complete [...]
This Pascal program is usefull in solving large tridiagonal linear systems. An example is the systems emerging from numerically integrating parabolic PDE’s by Finite Differences method. It was ported to Turbo Pascal from a Fortran 77 program. Its usage is very simple. All you have to do is to enter dimension of the system and [...]
This Pascal program finds the value of a Nth order polynomial: implementing Horner method without using any complex arithmetic in Fortran 77. Obviously, it can find complex values, for complex x’s, but without complex arithmetic. The program also uses ANSI codes to clear screen.
This little Fortran program, originally written in DOS, uses the arithmetic sequence to find the root of A. All you have to do is to enter A and a guess value . Caution: This program is very old; it uses Escape codes to clear the screen. In DOS, it needs the ANSI.COM driver. I haven’t [...]
