1、题目：一维小波变换，可多次分解 2、原理：卷积核变为Daubechies正交小波基h[]和g[]的交替形式。增加了多次分解的功能。-1, Title: one-dimensional wavelet transform decomposition can be repeated 2 Principle: convolution kernel becomes orthogonal Daubechies wavelet h [] and g [] alternate form. Decomp

用keil4编写C代码实现小波变换，以Daubechies小波基进行常用波形的尺度系数和小波系数提取(C code written in keil4, wavelet transform, Daubechies wavelet basis for the commonly used waveform scale coefficients and wavelet coefficients extraction)
