EIGENIND-SLP


The main purpose of the Mathematica codes EIGENIND-SLP is to compute the index or indices of a given approximate eigenvalue of a self-adjoint Sturm-Liouville problem. The boundary condition in the problem can be either separated or coupled.

The following are the files that you need to down-load, all in the text-format:

  1. README,

  2. Phi-matrix-pc,

  3. Phi-matrix-rglr,

  4. a-b-in-computations,

  5. compare-angles,

  6. compute-indices-pc,

  7. compute-indices-rglr, and

  8. count-zeros.
Moreover, 2 Mathematica notebooks containing examples are provided for your convenience:
  1. examples-pc.nb, and

  2. examples-rglr.nb.
