Isinvertible

WitrynaDefinition. An n × n matrix A is called invertible if there exists an n × n 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. WitrynaThe solution: You can choose between various decompositions, depending on the properties of your matrix A, and depending on whether you favor speed or accuracy. …

So to prove that a matrix has an inverse, calculate the determinant of the matrix, if it is different from 0, then the matrix is invertible. A non invertible matrix is called singular (inversion is not possible). Avoid the term inversible which is wrong.
