Matriks singular adalah matriks non-invertibel yaitu matriks tidak bisa di balik, jadi matriks singular jika diinvers atau di balik maka tidak bisa dilakukan penghitungan. A square matrix A is said to be non-singular if | A | â 0. AB = BA = I n. then the matrix B is called an inverse of A. For example, if a problem requires you to divide by a fraction, you can more easily multiply by its reciprocal. Equivalently, the set of singular matrices is closed and nowhere dense in the space of n-by-n matrices. This discussion on Suppose a is any 3×3 non singular matrix and (A -3I)(A- 5I) = O ,where I=I3 and O= O3. Nonsingular matrices are sometimes also called regular matrices.
