![]() For example, type:Īnd you will get information on the usage of "rref". It shows you how MATLAB commands should be used. (Can we always use this method to solve linear systems in MATLAB? Experiment with different systems.)Ĭommand "help" is a command you should use frequently. This command will generate a vector x, which is the solution of the linear system. The symbol between matrix A and vector b is a “backslash”. You can also solve the same system in MATLAB using command You now need to use command “rref”, in order to reduce the augmented matrix to its reduced row echelon form and solve your system:Ĭan you identify the solution of the system after you calculated matrix C? You have now generated augmented matrix Aaug (you can call it a different name if you wish). In order to solve the system Ax=b using Gauss-Jordan elimination, you first need to generate the augmented matrix, consisting of the coefficient matrix A and the right hand side b: To generate a column vector b (make sure you include the prime ’ at the end of the command). This command generates a 3x3 matrix, which is displayed on your screen.
