C++/CLI側 void CPP(int% a) { a++; }C#側 int a = 0; CPP(ref a); ->a==1トラッキング参照とかいうのだそうで http://ja.wikipedia.org/wiki/C++/CLI

short[] x = new short[10]; double[] y; x.CopyTo(y,0);だとエラー short[] x = new short[10]; double[] y = new double[x.Length]; x.CopyTo(y,0);だと正常．

double[][] Original = new double[num][]; ... double[] jointdata = new double[1000 * num]; for (int i = 0; i < num; i++) { Original[i].CopyTo(jointdata, 1000*i); }これってCopyToだからコピーなんだよな．参照とかポインタだけ渡せないのかな… (un…
