                  DAESA, \ul Differential-\ul Algebraic \ul Equations 
                  \ul Structural
                  \ul Analyzer, is a MATLAB tool for structural analysis of
                  differential-algebraic equations (DAEs).  It allows
                  convenient translation of a DAE system into MATLAB and
                  provides a small set of easy-to-use functions. DAESA can
                  analyze systems that are fully nonlinear, high-index,
                  and of any order.  It determines structural index,
                  number of degrees of freedom, constraints, variables
                  to be initialized, and suggests a solution scheme. The
                  structure of a DAE can be readily visualized by this
                  tool. It also can construct a block-triangular form of
                  the DAE, which can be exploited to solve it efficiently
                  in a block-wise manner.

                  This paper describes the theory and algorithms underlying the
                  code.",
