public static double[][] ConvertToDouble(int[,] arr , int r , int c)
{
double[][] matrix = new double[r][c];
for(int i=0;i<r;i++)
{
for(int j=0;j<c;j++)
{
matrix[i][j] = Convert.ToDouble(arr[i,j]); //the error comes in this line
}
}
return matrix;
}
iam here trying to create a function that converts int[,] to double[][] and i got a System.NullReferenceException
