S Using the MATH Menu
In the RUN • MAT mode, pressing (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}
•{2s2} ... {inputs a 2 × 2 matrix}
•{3s3} ... {inputs a 3 × 3 matrix}
•{
