Dynamic model allocating method based on matrix transformation

The invention relates to a dynamic model allocating method based on matrix transformation. The method comprises the steps of firstly, transforming and generating complex models into model files which can be loaded conveniently by programs according to dynamic model operation requirements in expense analysis and assessment processes, and designing transformation matrixes to be adapted to uncertain input and output parameters of different models; dynamically calling successfully registered models, analyzing input matrix content and loading corresponding data for calculation; and finally, graphically displaying and saving output results according to analysis of the output matrix content. By means of the dynamic model allocating method, dynamic model allocation based on matrix transformation is designed and achieved, all kinds of models in expense analysis and assessment processes can be integrated and called widely, the problem that staff members fail to use complex models is solved effectively, the complexity a
