使用“ WaveletStudio”将wavelet应用于wave文件

Question

我尝试在VS上使用wavelet来计算wave文件的WaveletStudio，但该库没有很好的文档，我不确定我所做的一切。

这是我在matlab上的代码

[cA,cD]= dwt(x1(:,1),'sym6');

这是VS上的代码

var sample = buf.Samples;
double[] doubleArray = Array.ConvertAll(sample, x => (double)x);

Signal sign = new Signal(doubleArray);
var wavelet = MotherWavelet.LoadFromName("sym6");
var output = DWT.ExecuteDWT(sign, wavelet,2, 
SignalExtension.ExtensionMode.AntisymmetricHalfPoint);

有人可以帮我吗？ 谢谢。

输出matlab： 3,16320801207017e-07 -1,01583359677462e-05 -3,47844682047843e-06 1,14694820511622e-05 3,39252240372775e-07 8,97279990863433e-06 1,15038653611192e-05 2,43046421129216e-06 -1,61369908206498e-05 1,32412854950234e-05 -1,08862917135995e-05

VB中的输出： 我显示十个值，与matlab不相等并且出现两次（索引0和1）

for (int i = 0; i <10; i++)

{
   Console.WriteLine(i+1 + ":"+outp.Index + ":" + outp.Details[i]+"/"+outp.Approximation[i]);
}

结果：
