Let $\mathbf A$ be an $m \times n$ matrix over a set $S$.
The individual $m \times n$ elements of $S$ that go to form $\mathbf A = \sqbrk a_{m n}$ are known as the elements of the matrix.
The element at row $i$ and column $j$ is called element $\tuple {i, j}$ of $\mathbf A$, and can be written $a_{i j}$, or $a_{i, j}$ if $i$ and $j$ are of more than one character.
If the indices are still more complicated coefficients and further clarity is required, then the form $a \tuple {i, j}$ can be used.
Note that the first subscript determines the row, and the second the column, of the matrix where the element is positioned.
