The MATLAB package ABLEpack contains a set of functions for 
solving non-Hermitian eigenvalue problems 
      A*x = lambda*x 
or 
      A*x = lambda*B*x
where A and B are generally non-Hermitian (non-symmetric). 

The underlying algorithms is the adaptive block Lanczos method 
with optional shift-and-invert spectral transformation. 

The ABLEpack consists of the following subdirectories: 

    DOC/:      documents related to ABLE
    SRC/:      core MATLAB source codes 
    TESTING/:  testing and demo codes
