[Numpy-discussion] higher accuracy in diagonialzation

Dear all,

I am now diagonalizing a 200-by-200 symmetric matrix. But the two methods,
scipy.linalg.eigh and numpy.linalg.eigh give significantly different result.
The results from two methods are different within 10^-4 order. One of them
is inaccurate or both two of them are inaccurate within that range. Which
one is more accurate? or Are there any ways to control the accuracy for
diagonalization? If you have some idea please let me know.
