SymPy不过是一个Python库,比如NumPy、Django,甚至是Python标准库sys或re中的模块。这意味着SymPy不向Python语言添加任何内容。Python语言固有的局限性也是SymPy固有的。这也意味着sypy会尽可能地使用Python习惯用法,这使得那些已经熟悉Python编程的人可以轻松地使用sypy编程。作为一个简单的例子,SymPy使用Python语法来构建表...

例如,Python 中可能存在多个返回值,但 C 或 Fortran 中不存在。另一个例子是 Fortran 和 Python 支持复数,而 C 不支持。 propertyresult_variables 返回OutputArgument、InOutArgument 和 Result 的列表。 如果存在返回值,则它们位于列表的末尾。 propertyvariables 返回可能在例程中使用的所有变量的集合。 对于具有无...
org/python-sympy-plane-projection-method/In Sympy, the function Plane.projection() is used project the given point onto the given plane along the plane normal which means, the projection is along the normal vector direction of the plane.

In this chapter, we introduce SymPy. This Python library provides special mathematical functions and polynomials as well as powerful symbolic mathematics. You can include SymPy in your programs by means of the following directive: import sympy as sp....

If the indefinite Integral returned by this function is an instance of NonElementaryIntegral, that means that the Risch algorithm has proven that integral to be non-elementary. Note that by default, additional methods (such as the Meijer G method outlined below) are tried on these integrals, ...
