Aim of the applet

This applet allows to solve a system of equations by Gaussian elimination.

Ofrece también la posibilidad de obtener la matriz inversa de A mediante el método Gauss-Jordan.

Input data

Solving the system AX=B

• Coefficient matrix, A
• Right side vector, B

Calculating the inverse matrix

• Coefficient matrix, A

The button "Calculate" will display the corresponding blocks.

The user may specify the order of the matrix, as well as the number de digit of the cells, from the block "Configuration".

Output data

The applet shall, in the corresponding block, the following information:

• Gaussian elimination result
• Gauss-Jordan method result
• Finding solution

First steps

• Write a system of 3 equations that has a unique solution.
• Build a system whose solution is (1,2,3). Calculates the inverse of A and verifies that get the solution when multiplied by the right side vector.
• Find a system without solution and another whose only solution is (0,0,0).
