摘要
MATLAB作为功能强大的数学软件,在很多领域有着成功的应用;在数字信号处理、语音信号处理方面,其大量的函数极大地简化编程、计算,提高了效率;小波分析是近30多年来发展起来的新兴学科,是傅立叶变换突破性的发展,为很多领域和工程应用提供全新的工具;在MATLAB环境下,集成了小波分析工具箱,可以很方便地进行小波分析、计算、分解信号;同时,还可以根据需要,把新构造的小波添加到工具箱。
As a powerful software, MATLAB is used widely in varies areas. Its build-in functions simplifies coding, calculating, and therefore is ef- fective. Wavelet analysis is new developed technique in recent 30 years, it also is break-through development of Fourier transform. Tools of wavelet are integrated into the MATLAB system, are very convenient to analyze, calculate and decompose speech signal. And new wave- let can be added into the system if needed.
