WebJul 2, 2013 · A = matrix ( [ [1,2,3], [11,12,13], [21,22,23]]) By definition, the inverse of A when multiplied by the matrix A itself must give a unit matrix. The A chosen in the much praised … WebA matrix A is called invertible if there exists a matrix C such that A C = I and C A = I. In that case C is called the inverse of A. Clearly, C must also be square and the same size as A. The inverse of A is denoted A − 1. A matrix that is not invertible is called a singular matrix. A strange term, but you just have to memorize and get used to it.
