在Matlab中使用`wpdec`函数生成的DLL文件可以在C#中使用。您可以通过以下步骤来获取函数的返回值结构:
1. 在C#中声明DLL导入函数,以便您可以调用Matlab中的函数。例如:
```csharp
[DllImport("myDLL.dll")]
public static extern void wpdec(double[] inputSignal, int inputLength, int levels, string waveletName, ref IntPtr outputPtr, ref int outputLength);
```
2. 创建一个指向输出数组的指针,并在调用函数时将其传递给函数。例如:
```csharp
IntPtr outputPtr = IntPtr.Zero;
int outputLength = 0;
double[] inputSignal = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
int inputLength = inputSignal.Length;
int levels = 3;
string waveletName = "db4";
wpdec(inputSignal, inputLength, levels, waveletName, ref outputPtr, ref outputLength);
```
3. 将指针转换为输出数组。例如:
```csharp
double[] outputSignal = new double[outputLength];
Marshal.Copy(outputPtr, outputSignal, 0, outputLength);
```
4. 释放指针。例如:
```csharp
Marshal.FreeHGlobal(outputPtr);
```
这样,您就可以在C#中使用`wpdec`函数并获取其返回值结构。
