代码生成
符号计算的结果通常用于仅使用标准双精度算术的数值代码中。Symbolic Math Toolbox™ 提供用于直接从符号表达式生成 MATLAB 函数、Simulink Function 模块和基于 Simscape 语言的方程的函数。
使用这些函数，您可以将符号计算的结果转换为基于数值计算的函数，以便在程序的其他部分使用。使用生成的 MATLAB 函数不需要 Symbolic Math Toolbox 的许可证。您还可以将符号表达式转换为 C、Fortran、MathML 和 TeX 代码。

Estimate Model Parameters of a Symbolically Derived Plant Model in Simulink
Uses Simulink Design Optimization to estimate the unknown capacitance and initial voltage of a symbolically derived algebraic model of a simple resistor-capacitor (RC) circuit. The example solves the same problem and uses the same experimental data as Estimate Model Parameters and Initial States (Code) (Simulink Design Optimization), but uses the closed-form solution for the RC circuit instead of the differential form.
