Smooth eigendecomposition of real symmetric matrix function

Numerical computation of a smooth eigendecomposition of an n-by-n real symmetric matrix valued function of one real parameter

This function numerically computes the smooth eigendecomposition of an n-by-n real symmetric matrix-valued function FUN of one real parameter. The eigenvector matrices are orthogonal; the eigenvalues are real, arranged in decreasing order, and are assumed to be distinct for all values of the parameter. It is possible to continue a subset of the eigenvalues and eigenvectors.

A typical call to realSymmEigCont is:

[Tout,Uout,Dout,flag]=realSymmEigCont(FUN,tspan,params)

See the script example_realSymmEigCont.m for an example of how to use the function.

The command help realSymmEigCont displays information and functionality of the software.
