The results of generalized eigenvalue problem solved by 'eig' function are incorrect when the input matrices are hermitian.
A=hermitian matrix
B=hermitian matrix
eig(A,B).

The bug exists in 'libinterp/corefcn/EIG.cc':
So the hermitian_init is called without 'b' which is incorrect. The trivial fix is the following:
