- Of particular importance is his appreciation of the value of elementary hermitian matrices in numerical analysis.
- He discovered the rule for multiplying matrices in 1812 and it is almost certainly for this that he will be remembered rather than his other work.
- However he also worked on differential equations, matrices and other topics in algebra, continued fractions, geometry and number theory.
- The matrix is inserted at its base, the mould is adjusted to the desired width, molten lead is poured in to form a column, and the character is cast in the matrix at the bottom.
- These were then used to shape the matrixes from which the records were pressed.

- Rhombs of ferroan dolomite occur both in the fringe around the fossils and within the matrix of the concretion.
