| Q. |
What is the principle of factorization? |
| A. | there exists no inverse for a singular matrix |
| B. | determinant of an identity matrix is one |
| C. | every square matrix can be expressed as a product of a lower triangular matrix and upper triangular matrix |
| D. | every matrix can be expressed as a sum of a skew symmetric and a symmetric matrix |
| Answer» C. every square matrix can be expressed as a product of a lower triangular matrix and upper triangular matrix | |
| Explanation: the principle of factorization is that every square matrix can be expressed as a product of a lower triangular matrix and upper triangular matrix. on the basis of this fact, these lower and upper triangular matrices help us in finding the unknowns. | |
