A note on Cramer's rule given a class of "singular" matrices
The original version of Cramer’s rule [on determinants] relies on the hypothesis that in a matrix equation Ax = b, the matrix A is nonsingular. In this paper, we give conditions using the idea in Cramer’s rule, when matric A is singular. A particular class of singular matrices when the order n is at...

| Summary: | The original version of Cramer’s rule [on determinants] relies on the hypothesis that in a matrix equation Ax = b, the matrix A is nonsingular. In this paper, we give conditions using the idea in Cramer’s rule, when matric A is singular. A particular class of singular matrices when the order n is at least 3 is presented to illustrate the results. |
