WebDefinition. A 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. WebMatrix, the one with numbers, arranged with rows and columns, is extremely useful in most scientific fields. There...
