Abstract:
݊ × ݊ (݊ ≥ 5) matrices by reducing their sizes by four, it is known as the Cornice
Method. A determinant of matrices with the exception of the first and the last
entries, the entries of the 2nd row and (݊ − 1) − ݐh row, as well as the 2nd column
and (݊ − 1) − ݐh column are all zero. This called “Cornice Determinants” and
note as |ܥ× |(݊ ≥ 5). To obtain the form of this Cornice Ma
