Abstract:

A problem of using symbolic calculations in numerical software for solving stiff ordinary differential equations is discussed. The new tool for symbolic differentiation is described. The example of Jacobi matrix symbolic calculations into RADA5 method is presented to illustrate how this tool can be used for dense and sparse matrices.
