Rational entries of the form a/b and complex entries of the form a+bi are supported. Examples: `-5/12`

, `-2i + 4.5`

. Warning: JavaScript can only store integers up to 2^53 - 1 = 9007199254740991. Because this implementation uses a pair of integers to represent rational numbers, incorrect results can be produced when intermediate values are supposed to have numerators or denominator exceeding this maximum.

This calculator applies row reduction to the augmented matrix to compute the inverse.
