Question

从TXT数据集创建矩阵时遇到问题 TXT数据集 1,2，-1

3,4,5

6,7,8

我使用CreateMatrixFromFile从txt文件创建矩阵矩阵值已更改 e.x 矩阵[0,1] = 2 几次访问矩阵后矩阵[0,1] = 2更改为0或接近零

    public static unsafe Matrix<double> CreateMatrixFromFile(string[] fileData, int pointCount)
    {
        List<double> rawdata = new List<double>();
        int subLength = 0;
        for (int i = 0; i < fileData.Length; i++)
        {
            string[] subData = fileData[i].Split(',');

            subLength = subData.Length;
            for (int j = 0; j < subLength; j++)
            {
                double temp = Convert.ToDouble(subData[j]);
                rawdata.Add(temp);
            }
        }

        double[] dataArray = rawdata.ToArray();
        fixed (double* dataPtr = dataArray)
        {
            return new Matrix<double>(pointCount, subLength, (IntPtr)dataPtr);
        }

    }

EMGU：从TXT数据集创建Matrix <double>。多次访问后矩阵值改变
