As a powerful， easy-to-use and flexible computational tool， MATLAB not only has a wide range of applications in science and engineering， but also plays an important role in education and research. Its rich functionality， easy-to-use interface and extensive support make it one of the preferred tools in many fields. With MATLAB， users can easily perform complex mathematical operations， data analysis and algorithm development， which promotes the development and innovation of science and technology.
自然对数e是一个很迷人的数字，就在上个世纪九十年代，又有人偶然发现了关于自然对数e的两个计算公式。举个例子:如果您借了1000元，年利率是20%，按单利计算一年后需要还:1000元 × = 1000元 + 200元 = 1200元。
e在数学中代表自然常数，是自然数对数函数的底数，又称为欧拉数，是一个无限不循环的小数，值约为小数点后一百位，约为2.71828182845904，与圆周率π和虚数单位i一样，都是数学中最为重要的常数之一。
