private pure function get_element(this, row, col) result(element)

Retrieves the element at position (row, col) of the original matrix. See the LAPACK documentation, element $a_{ij}$ of the original matrix is stored at position $(kd + 1 + i - j, j)$ if uplo = "U" and at position $(1 + i - j, j)$ if uplo = "L" in the banded storage.
