For information about function input from the MATH function menu, see “Using the MATH
Menu” described below.

Tolerance cannot be specified in the Math input/output mode. If you want to specify
tolerance, use the Linear input/output mode.
*
4
For
Σ calculation in the Math input/output mode, the pitch is always 1. If you want to specify
a different pitch, use the Linear input/output mode.

This is the number of bytes for a 2 × 2 matrix.
u Using the MATH Menu
In the Run-Matrix mode, pressing
4(MATH) displays the MATH menu.
You can use this menu for natural input of matrices, derivatives, integrals, etc.
• { MAT } ... {displays the MAT submenu, for natural input of matrices}
• { 2
