I have a 3x3 matrix for which i want to calculate eigenvalues/-vectors. Using the function "ippmEigenValuesSym_m_64f" i get an ippStsSingularErr error meaning the matrix is singular, which is not the case.
The function "ippmLUDecomp_m_64f" however performs without problems on the same matrix.
The matrix elements are in the range of 1e-5 to 1e-6. Scaling the matrix by a factor of 10 yields valid results.
Are there any requirements on the size of the elements for the eigenvalue decomposition?
