Eigenvalues of Ax =
Bx with band symmetric A and B
Division of Numerical and Applied Mathematics National Physics Laboratory, Teddington, Middlesex, UK
Describes an efficient algorithm for the calculation of specified eigenvalues of Ax =
Bx with band symmetric A and B, the latter being positive definite. Each eigenvalue is isolated using the Sturm sequence property of leading principal minors of A
B and is then computed accurately using a modified version of successive linear interpolation.
