Symbolic Math Toolbox 快速入门
Symbolic Math Toolbox™ 提供用于求解、绘制和处理符号数学方程的函数。您可以创建、运行和共享符号数学代码。在 MATLAB® 实时编辑器中，您可以获取符号工作流的下一步建议。该工具箱提供微积分、线性代数、代数方程和微分方程、方程简化以及方程操作等常见数学领域的函数。
您可以使用 Symbolic Math Toolbox 以解析方式执行微分、积分、简化、变换和方程求解。您可以执行维度计算并在单位之间进行转换。可通过解析方式或使用可变精度算术执行计算，结果以数学排版形式显示。
您可以将符号工作作为实时脚本与其他 MATLAB 用户共享，也可以将其转换为 HTML、Word、LaTeX 或 PDF 文档。您可以直接从符号表达式生成 MATLAB 函数、Simulink® Function 模块和 Simscape™ 方程。
