Examples
Basic Examples (1)
Use DependentVariableQ to identify a variable that depends on a single variable:
Scope (3)
Use DependentVariableQ with a list of variables that depend on a single variable:
Use DependentVariableQ with a variable that depends on two variables:
These are not dependent variables:
Properties and Relations (4)
Use DependentVariableQ with the resource function SolutionRulesToFunctions to convert solution rules to function rules in a given list containing rules whose left-hand side don't match with a variable that depends on other variables:
Use DependentVariableQ with the resource function SolutionRulesToFunctions on a more complicated list:
Use DependentVariableQ with the resource function SymbolToSubscript:
Use DependentVariableQ with the resource function FormalizeSymbols:
Possible Issues (1)
DependentVariableQ only identifies dependent variables that have the formats x[var] or x[vars]:
