Entering and Editing Variable Values
When you enter or edit a value for a variable in the interactive solver
editor, the new value is stored in memory to that variable.
You can enter an expression for a variable value. It is evaluated when
you move to the next variable. Expressions must resolve to real numbers
at each step during the iteration.
You can store equations to any
VARS Y
.
VARS
variables, such as
Y
1
or
r
6
,
and then reference the variables in the equation. The interactive solver
editor displays all variables of all
Y=
functions referenced in the equation.
