通过一系列教学实例，帮助学生很好的理解matlab中的符号运算实现微分、积分（定积分与不定积分）、极限、级数、绘图等常用功能，几乎可以推导高数中的绝大部分公式，也可用于理论公式推导。-Through a series of teaching examples to help students a good understanding of symbolic computation matlab achieve differentiation, integration (with the definite integral indefinite integral), ultimate, series, graphics and other commonly used functions can be derived almost most of the high number of formulas can also be used to derive theoretical formulas.
