Ident

Function: ident (<n>) Returns an <n> by <n> identity matrix.

n : matrix ([a[11], a[12]], [a[21], a[22]]);
p_n : determinant (x * ident(2) - n), expand;
at (x . x - a[22]*x - a[11]*x + a[11]*a[22] - a[12]*a[21], [x = n]);

There are also some inexact matches for ident. Try ?? ident to see them.
