小波变换及小波基对不同尺度的haar及db小波连续变换的系数值的三维图与傅里叶变换的比较-Comparison of three-dimensional map of the wavelet transform and wavelet bases on different scales haar continuous and db wavelet transform coefficient values ​ ​ an

自定义小波变换，可以随便使用各个小波基函数进行小波变换(A custom wavelet transform can be used to transform wavelet transform randomly.)
