How can I put a matrix into reduced row echelon form on FX9750G / CFX9850G series?
Use the program ROWREDA. This is built into the FX-9750G Plus and CFX-9850GB Plus, and can be loaded using the following procedure: 1. Press [MENU]. 2. Select PRGM by moving the highlight to PRGM and pressing [EXE]. Alternatively you can press the [log] key (which is the key for B). 3. Press [F6]. 4. Press [F5] (LOAD). 5. Cursor down to “U.S.A” and then press [EXE]. 6. Press the cursor down several times until ROWREDA is highlighted, then press [EXE]. For other calculators in this series that do not have the program built-in, it can be downloaded from the following page: http://www.casioeducation.com/downloads/4AB30298-DA84-4D3A-82A8-9088C88C19BF To use the program, go to MAT mode and store the matrix in Matrix A. After executing the program, the result will be in Matrix R.
