15、y”（缩写为Matlab）这就是Matlab最早的雏形。开发的最早的目的是帮助学校的老师和学生更好的授课和学习。从Matlab诞生开始，由于其高度的集成性及应用的方便性，在高校中受到了极大的欢迎。由于它使用方便，能非常快的实现科研人员的设想，极大的节约了科研人员的时间，受到了大多数科研人员的支持，经过一代代人的努力，目前已发展到了7.X版本。 Matlab是一种解释性执行语言，具有强大的计算、仿真、绘图等功能。由于它使用简单，扩充方便，尤其是世界上有成千上万的不同领域的科研工作者不停的在自己的科研过程中扩充Matlab的功能，使其成为了巨大的知识宝库。可以毫不夸张的说，哪怕是你真正理解了一个工具箱，那么就是理解了一门非常重要的科学知识。科研工作者通常可以通过Matlab来学习某个领域的科学知识，这就是Matlab真正在全世界推广开来的原因。目前的Matlab版本已经可以方便的设计漂亮的界面，它可以像VB等语言一样设计漂亮的用户接口，同时因为有最丰富的函数库（工具箱），所以计算的功能实现也很简单，进一步受到了科研工作者的欢迎。另外，,Matlab和其他高级语言也具有良好的接口，可以方便的实现与其他语言的混合编程，进一步拓宽了Matlab的应用潜力。可以说，Matlab已经也很有必要成为
