Main features

  • Analyze DAEs that can be fully nonlinear, implicit, high-index, and high-order
  • Determine (structural) index, degrees of freedom, constraints, and which variables/derivatives need initial values
  • Visualize the original structure of a DAE and its block upper triangular form
  • Suggest a solution scheme for a Taylor series method

DAESA is a Matlab software for structural analysis (SA) of differential-algebraic equations (DAEs). It allows convenient translation of a DAE into a Matlab function, and provides a good many useful functions for understanding and exploring the DAE's structure. ​(简体中文链接)
