DSolve::dvlen NDSolve::dvlen NDSolveValue::dvlen ParametricNDSolve::dvlen ParametricNDSolveValue::dvlen RSolve::dvlen

Details

This message is generated when the dependent variable occurs with a number of arguments that is not equal to the number of independent variables.
Off[message] switches off the message; On[message] switches it on. For example: Off[DSolve::dvlen].

Examples

Here f[0, x] has two arguments and there is only one independent variable:

Wolfram Language code: DSolve[f'[x] == f[0, x], f[x], x]

This shows a valid input to NDSolve using f[0] as the independent variable:

Wolfram Language code: DSolve[f[0]'[x] == f[0][x], f[0][x], x]
