摘　　要：分析了动态连接库(DLL)的工作原理,介绍了Labview环境下动态连接库(DLL)的构建和调用方法,在分析Mallat正交小波变换快速算法的基础上,构造了小波变换动态连接库,借助于Labview的高级语言编程接口功能,通过进一步设计,将Mallat算法引入到Labview环境中,扩充了Labview的功能,并对Labview下的Mallat小波变换算法进行了实验验证。The principle of dynamic link library(DLL)is discussed in this paper,and then the building and calling method of DLL functions under Labview is introduced.Based on making a study of the fast algorithm of Mallat orthogo-nal wavelet Transform,a dynamic link library of the wavelet transform is designed.By using this DLL and the advanced programming interfaces of Labview,the Mallat algorithm is realized in Labview language in the paper,this development work expands the function library of Labview,an experiment is made later by using this method.
