# scipy.linalg.lapack.chegvx

scipy.linalg.lapack.chegvx(a, b[, itype, jobz, range, uplo, vl, vu, il, iu, abstol, lwork, overwrite_a, overwrite_b]) = <fortran function chegvx>

  Wrapper for `chegvx`.

  Parameters:

  Returns:
    w rank-1 array(‘f’) with bounds (n)
    z rank-2 array(‘F’) with bounds ((jobz == ‘V’?MAX(0, n):0),(jobz == ‘V’?(range == ‘I’?1 - il + iu:MAX(1, n)):0))
    m int
    ifail rank-1 array(‘i’) with bounds ((jobz == ‘N’?0:n))
