摘要
在VAX-8300计算机上,使用编译原理,研制了代替手工求解多种有解析表达式的函数的导数、偏导数、混合导数、泰勒级数展开等的方法。由于采用符号运算而不是数值计算,故推导结果迅速精确,所得的结果是进一步研究计算机代数的基础模块。
This paper studies a method to find various formulated functions diff- erention,partial differention,mixtural differention and Taylor expansion. This method,instead of artificial computation,applies principles of comp- iler design to automatically solve them by using the VAX-8300 computer. Because of making use of symbolic operation(nonnumariral value calculat- ion),the derived results are accurate and fast.They can be considered as elemental models for advanced study of computer algebra.
