我有像这样的ilnumerics逻辑对称矩阵
0 0 0 0 0 0 1 1 1 1
0 0 0 0 0 1 0 1 1 1
0 0 0 0 0 1 1 0 1 1
0 0 0 0 0 1 1 0 0 1
0 0 0 0 0 1 1 1 1 0
0 1 1 1 1 0 0 0 0 0
1 0 1 1 1 0 0 0 0 0
1 1 0 0 1 0 0 0 0 0
1 1 1 0 1 0 0 0 0 0
1 1 1 1 0 0 0 0 0 0
我想获得值== 1
的所有维度(行和列)结果= (0,6),(0,7),(0,8),(0,9) (1,5),(1,7),(1,8),(1,9) (2,5),(2,6),(2,8),(1,9) (3,5),(3,6),(3,9) (4,5),(4,6),(4,7),(4,8)
使用C#中的ilnumerics库有更快的方法吗?
编辑:这是我的解决方案
ILNumerics.ILLogical matrixThreshold;
..... Some C# code
for (int i = 0; i < matrixThreshold.Length; i++)
for (int j = i + 1; j < matrixThreshold.Length; j++)
if (matrixThreshold.GetValue(i, j) == 1) Console.Write("({0},{1}){2}", i, j, Environment.NewLine);
答案 0 :(得分:2)
ILLogical L = ILMath.rand(10, 12) > 0.5;
>L
Logical [10,12]
[0]: 0 0 0 1 1 1 0 0 0 0 1 1
[1]: 0 1 1 1 0 1 1 1 1 0 1 0
[2]: 0 1 1 1 1 1 0 1 1 0 1 1
[3]: 0 0 0 0 0 1 0 0 0 0 1 0
[4]: 0 0 0 0 0 0 1 0 1 1 0 0
[5]: 0 0 1 0 0 1 0 0 1 1 1 1
[6]: 1 0 1 0 1 1 0 1 0 1 0 1
[7]: 1 1 1 0 1 1 0 1 1 1 0 1
[8]: 1 0 0 1 1 1 0 0 1 0 0 0
[9]: 1 1 1 1 0 0 0 0 1 1 0 0
将列/行索引写成对:
ILArray<int> C = 1;
ILArray<int> R = ILMath.find(L, 0, C);
// C now holds the column indices, R the row indices
for (int i = 0; i < C.Length; i++) {
System.Diagnostics.Debug.WriteLine("({0},{1})", R.GetValue(i), C.GetValue(i));
}
