Matlab窗体Figure嵌入到WPF

萌新一只，想着把遇到的问题和大家分享一下。
matlab的代码如下，

[x,y] = meshgrid(-2:0.1:2);
z = y.*exp(-x.^2-y.^2);
figure(1)
surf(x,y,z)

output_args=1;

c#的程序如下，

public partial class MainWindow : Window

        public MainWindow()

        public class ControlHost : HwndHost  //派生HwndHost
        {
   
            [DllImport("user32.dll")]
            private static extern int SetParent(IntPtr hWndChild, IntPtr hWndParent);
            
            [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
            private static extern uint SetWindowLong(IntPtr hwnd, int nIndex, uint newLong);
