This message is generated when the matrix eigenvalue algorithm fails to solve for all of the eigenvalues of a matrix.
This message is currently used only for functions that compute eigenvalues of symbolic matrices.
This message indicates an internal failure that should only occur under unusual conditions, such as failure to recognize a combination of symbols that simplifies to zero.
If you see this message in an example where it is not expected, please contact Technical Support.
Off[message] switches off the message; On[message] switches it on. For example: Off[General::eival].
