Comparative Analysis of the Mathematical Methods Accuracy of the Parametric Identification of an Aeroengine Gas Path

The study This study is devoted to various methods for solving systems of linear algebraic equations built on a diagnostic matrix of parameters of an aeroengine gas-air path. Exact, iterative and optimization methods for solving SLAE for the performed problem were considered. Calculations were made according to various algorithms using object-oriented programming language Python (v3.6.9), proprietary multi-paradigm programming language MATLAB 2018b and computer-aided design system PTC MathCAD Prime 8.0.0.0. a mathematical analysis of the matrix under study was performed. Estimates of the above methods effectiveness were made on the average error basis. The results were analyzed and promising methods for solving the problem were identified.
