Interpolation::incon ListInterpolation::incon InterpolatingFunction::incon

Details

  • This message is generated when partial derivatives are not specified uniformly in the input to the indicated function.
  • In multidimensional interpolation, derivatives must be specified in the same way at all interpolation points.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[Interpolation::incon].

Examples

Basic Examples  (1)

An error occurs because derivatives are specified for only some of the points:

Wolfram Language code: Interpolation[{{1, 1, {2, {0, 0}}}, {1, 2, {3, {0, 0}}}, {1, 3, {4, {0, 0}}}, {1, 4, {5, {0, 0}}}, {2, 1, 3}, {2, 2, 4}, {2, 3, 5}, {2, 4, 6}, {3, 1, 4}, {3, 2, 5}, {3, 3, 6}, {3, 4, 7}, {4, 1, 5}, {4, 2, 6}, {4, 3, 7}, {4, 4, 8}}]

This shows valid input to Interpolation with specifications for the first partial derivatives:

Wolfram Language code: sampledata = Flatten[Table[{x, y, {x + y, {0, 0}}}, {x, 4}, {y, 4}], 1]
Wolfram Language code: Interpolation[sampledata]

Clear the value of sampledata.

Wolfram Language code: Clear[sampledata]
