LabVIEW是一种程序开发环境，由美国国家仪器（NI）公司研制开发的，类似于C和BASIC开发环境，但是LabVIEW与其他计算机语言的显著区别是：其他计算机语言都是采用基于文本的语言产生代码，而LabVIEW使用的是图形化编辑语言G编写程序，产生的程序是框图的形式。-LabVIEW is a program development environment from National Instruments [NI] the company developed, similar to C and BASIC development environment, but computer language LabVIEW with other significant difference is: in other computer languages are used in text-based languages have code, while LabVIEW using the G graphical programming language editors, resulting in the procedure are the form of block diagram.
