Analysis on Algorithm of Wavelet Transform And Its Realization in C Language.

Wavelet analysis is a branch of mathematics which formed and developed in the late 1980s. With the development and maturation of wavelet theory and application, wavelet transform has been widely applied to most aspects of engineer, but usually only use the MATLAB wavelet toolbox to do program. In order to reflect the algorithm and connotation of wavelet transform deeply, we should write the program ourselves to realize some functions. In this paper, we will introduce the theory and algorithm analysis on Mallat algorithm of wavelet transform. And then, we will give the program flowchart of this algorithm which is realized in C language. Finally we will take the DB2 wavelet for example to program the wavelet transform in C language, and using MATLAB to draw waveform figures of using this algorithm and MATLAB wavelet toolbox to compare the results.
