u TABLE — Recalling table setup and content data
• { Start } / { End } / { Pitch } ... {table range start value}/{table range end value}/{table value
increment}
• { Result *
1
} ... {matrix of table contents}
*
1
The Result item appears only when the TABLE menu is displayed in the Run-Matrix and
Program modes.
u RECURSION — Recalling recursion formula*

• { RANGE } ... {table range data menu}
• { Start } / { End } ... table range {start value}/{end value}

}
*
1
An error occurs when there is no function or recursion formula numeric table in memory.
*
2
“Result” is available only in the Run-Matrix and Program modes.
*
3
Table contents are stored automatically in Matrix Answer Memory (MatAns).
u EQUATION — Recalling equation coefficients and solutions*
1
*
2
• { SimRes } / { SimCoef } ... matrix of {solutions*
3
}/{coefficients} for linear equations with two
through six unknowns*
4
• { PlyRes } / { PlyCoef } ... matrix of {solution}/{coefficients} for high-order equations from 2nd
to 6th degree
*
1
Coefficients and solutions are stored automatically in Matrix Answer Memory (MatAns).
*
2
The following conditions cause an error.
- When there are no coefficients input for the equation
- When there are no solutions obtained for the equation
*
3
When the “Infinitely Many Solutions” or “No Solution” message is displayed, the
calculation result is Rref (reduced row echelon form).
*
4
Coefficient and solution memory data for a linear equation cannot be recalled at the same
time.
u FINANCE — Recalling financial calculation data
• { n } / { I %} / { PV } / { PMT } / { FV } ... {payment periods (installments)}/{annual interest rate}/
{present value}/{payment}/{future value}
• {
P/Y } / { C/Y } ... {installment periods per year}/{compounding periods per year}
u Str — Str command
• { Str } ... {string memory}
