n | - dimension of the matrix | |
k | - first active column | |
ldt | - leading dimension of T | |
which | - eigenvalue sort order |
T | - the upper (quasi-)triangular matrix | |
Z | - the orthogonal matrix of Schur vectors | |
wr | - pointer to the array to store the computed eigenvalues | |
wi | - imaginary part of the eigenvalues (only when using real numbers) |
Both T and Z are overwritten.
This routine uses LAPACK routines xTREXC.
