Type: Command
Description: Dependent Variable Command: Specifies the dependent variable (and its plotting range for TRUTH plots).
The specification for the dependent variable name and its plotting range is stored in the reserved variable PPAR as follows:
•If the argument is a global variable name, that name replaces the dependent variable entry in PPAR.
•If the argument is a list containing a global name, that name replaces the dependent variable name but leaves unchanged any existing plotting range.
•If the argument is a list containing a global name and two real numbers, or a list containing a name, array, and real number, that list replaces the dependent variable entry.
•If the argument is a list containing two real numbers, or two real numbers from levels 1 and 2, those two numbers specify a new plotting range, leaving the dependent variable name unchanged. (LASTARG returns a list, even if the two numbers were entered separately.)
The default entry is Y.
The plotting range for the dependent variable is meaningful only for plot type TRUTH, where it restricts the region for which the equation is tested, and for plot type DIFFEQ, where it specifies the initial solution value and absolute error tolerance.
