| Abstract: | 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. |
