Details

  • This message is generated when the order of the derivative in a differential equation is not an integer.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[DSolve::ndord].

Examples

Basic Examples  (1)

An error occurs because of an incorrect use of Derivative in the input:

Wolfram Language code: NDSolve[{Derivative[f][f][x] == f[x], f[1] == 1}, f, {x, 1, 2}]

This shows a valid specification of a derivative in the input to NDSolve:

Wolfram Language code: NDSolve[{Derivative[1][f][x] == f[x], f[1] == 1}, f, {x, 1, 2}]
