INSTALLATION ============ To unpack and install: tar zxvf Gelim-1.0.0.tar.gz cd Gelim-1.0.0 make USAGE ===== Gelim can be run in two modes: Interactive, and Commandline. In the interactive mode, it asks for the size of the equation system and lets You enter the values for the coefficient matrix. In the commandline mode, Gelim determines the size of the coefficient matrix by the amount of coefficient parameters passed to it at start-up. Let's solve the following equation system: 1x + 3y + 2z = 4 3x - 5y + 4z = -6 5x + 7y + 6z = 8 * Interactive mode Just start Gelim the usual way $ ./gelim Gelim will ask for the size of the system. In this case, we have a 3 by 3 coefficient matrix, so the size is 3. Then Gelim asks for each of the numbers in the order they appear above, from left to right, top to bottom. * Commandline mode This one is really simple, and suitable for ex. when called from a script. $ ./gelim 1 3 2 4 3 -5 4 -6 5 7 6 8 Gelim will give the following answer: -0.800000 1.200000 0.600000 ... this simply means that x = -0.8, y = 1.2 and z = 0.6 Have fun! :D
