我有一個MxNx3矩陣,我想用MWArray將它轉換爲matlab。
這是我的代碼,但是沒有CTOR。
有什麼辦法可以做到嗎?將C#數組轉換爲MWarray Matlab

RGBImage image = _currentImage as RGBImage; 

int height = image.Height; 
int width = image.Width; 

//transform the 1D array of byte into MxNx3 matrix 
byte[, ,] rgbByteImage = new byte[3, height, width]; 
if (image[0].Bpp > 16) 
{ 
    for (int i = 0; i < height; i++) 
    { 
     for (int j = 0, k = 0; k < width; j = j + 3, k++) 
     { 
      rgbByteImage[0, i, k] = image[0].Data[i * width + j]; 
      rgbByteImage[1, i, k] = image[0].Data[i * width + j + 1]; 
      rgbByteImage[2, i, k] = image[0].Data[i * width + j + 2 ]; 
     } 
    } 
} 

MWNumericArray tempArr = new MWNumericArray(rgbByteImage);

RGBImage image = _currentImage as RGBImage; 

int height = image.Height; 
int width = image.Width; 

//transform the 1D array of byte into MxNx3 matrix 

byte[ , , ] RGBByteImage = new byte[3,height, width]; 

if (image[0].Bpp > 16) 
{ 
    for (int i = 0; i < height; i++) 
    { 
     for (int j = 0, k = 0; k < width; j = j + 3, k++) 
     { 
      RGBByteImage[0, i, k] = image[0].Data[3 * i * width + j]; 
      RGBByteImage[1, i, k] = image[0].Data[3 * i * width + j + 1]; 
      RGBByteImage[2, i, k] = image[0].Data[3 * i * width + j + 2]; 
     } 
    } 
} 

MWNumericArray matrix = null; 
matrix = new MWNumericArray(MWArrayComplexity.Real, MWNumericType.Int8, 3,height, width); 
matrix = RGBByteImage; 

這是我所發現的。

也有一個很好的教程在這裏 http://domoreinlesstime.wordpress.com/2013/01/26/access-matlab-from-c/

請注意,您有正確的refernce到MWArray.dll文件(64或86)。我浪費了一天左右的時間。
