How to solve dynamic two dimensional array indexing error?

Question

C++ / C#

We need to find the smaller value in a dynamic two-dimensional array. By and large, the whole code is ready, but in the indexing places it gives the error C2676 "binary "[": "Matrix" does not define this operator or conversion to a type acceptable to the built-in operator"

Here is the code:

template<typename T, size_t rows, size_t cols>
inline int Matrix<T, rows, cols>::findSmallest(Matrix<T, rows, cols>& m)
{
    int resNum = m[0][0];
    for (size_t i = 0; i < rows; i++)
    {
        for (size_t j = 0; j < cols; j++)
        {
            if (m[i][j] < resNum)
            {
                resNum = m[i][j];
            }
        }
    }
    return resNum;
}

PS Here is the definition in the class:
int findSmallest(Matrix<T, rows, cols>& m);

Answer 1

You work with matrix as if it were an array, but you don't have it as an array. Either redefine the [] operator, or somehow output from matrix to T**.

Answer 2

Why do i and j both count as rows? It seems to me that there should be an out of bonds exception. I should be rows, j- columns.
