u Using the MATH Menu
In the RUN • MAT mode, pressing 4(MATH) displays the MATH menu.
You can use this menu for natural input of matrices, differentials, integrals, etc.
• {MAT} ... {displays the MAT submenu, for natural input of matrices}
• {2
×2} ... {inputs a 2 × 2 matrix}
• {3
×3} ... {inputs a 3 × 3 matrix}
• { m × n } ... {inputs a matrix with m lines and n columns (up to 6
× 6)}
• {logab} ... {starts natural input of logarithm log ab}
• {Abs} ... {starts natural input of absolute value |X|}
• { d / dx } ... {starts natural input of linear differential
