Details

  • This message is generated when the first argument in InterpolatingPolynomial is a list of pairs and at least two pairs have the same first element.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[InterpolatingPolynomial::ipdup].

Examples

Basic Examples  (1)

An error occurs because the first and last pair have the same first element:

Wolfram Language code: InterpolatingPolynomial[{{2, 0}, {3, 1}, {2, 2}}, x]

This shows valid arguments in InterpolatingPolynomial:

Wolfram Language code: InterpolatingPolynomial[{{2, 0}, {3, 1}, {0, 2}}, x]
