LabVIEW是一种程序开发环境，由美国国家仪器(NI)公司研制开发，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 kind of program development environment, developed by the U.S. national instrument (NI), similar to C and BASIC development environment, but the LabVIEW and other computer language is a significant difference: the other computer language is the language based on text generate code, and the use of LabVIEW is a graphical editing language G program, the program is in the form of block diagram.)
