You will write a Matlab user defined function that take a user input of a square matrix of any size. Your code will then perform checks to determine whether to use the Gauss-Seidel or Gauss-Jordan method to solve the system. Your code will then solve the system and return the values of xn. You may use third-party code for the Gauss-Seidel and Gauss-Jordan routines but you must cite the source of your code; comment it fully; write pseudocode for it and provide the appropriate data flow diagrams (visio). It is standard industry practice to reuse good code routines for complex mathematical operations. The following list of steps may help you: Ask user to input a matrix Check if the matrix is square - if not exit with message - If yes - check for diagonal dominance (as a function preferably) If yes- Gauss-Seidel If no- Check or positive-definiteness If yes- Gauss-Seidel - If no-Gauss-Jordan Output values of xn > End
