Questions of organising computations in spectral numerical-analytical methods of solving differential-algebraic equations systems and counting parametric root sensitivities of orders 1 and 2 of Windows-version tool SimStar/Win as spectral problems on matrix pencils are considered. Problems of computational process decomposition are examined. Computational complexity is determined. Comparison to Lancaster–Chu–Andrew method is held.
Keywords: parametric root sensitivity, spectral problems on matrix pencils, differential-algebraic equations systems.
