Interpolation::mixedp ListInterpolation::mixedp

Details

This message is generated when the derivatives specified in multidimensional interpolation are not symmetric.
Off[message] switches off the message; On[message] switches it on. For example: Off[Interpolation::mixedp].

The matrices that specify the second derivatives are not symmetric matrices:

Wolfram Language code: sampledata = Flatten[Table[{i, j, {i + j, {0, 0}, {{0, i}, {0, 0}}}}, {i, 3}, {j, 3}], 1]

Wolfram Language code: Interpolation[sampledata]

This shows valid data with consistent specifications of all partial derivatives.

Wolfram Language code: sampledata = Flatten[Table[{i, j, {i + j, {0, 0}, {{i, 0}, {0, 0}}}}, {i, 3}, {j, 3}], 1]

Wolfram Language code: Interpolation[sampledata]

Clear the value of sampledata.

Wolfram Language code: Clear[sampledata]
