eps | - the eigensolver context | |
n | - dimension of the matrix | |
k0 | - first active column | |
k1 | - last column to be ordered | |
ldt | - leading dimension of T |
T,S | - the upper (quasi-)triangular matrices | |
Q,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) |
T,S,Q and Z are overwritten.
This routine uses LAPACK routines xTGEXC.
