The computation for<br>both methods applies the reduction of (n-1)x(n-1) matrix and finds the determinant of 2x2<br>matrix. These techniques are different from the commonly practice - reducing an nxn matrix and<br>spreading cofactors of matrix - using Sarrus’s rule to compute the determinant of 3x3 matrix.<br>Different methods provide the same result, but each technique is more appropriate to specific<br>value of elements in varied matrices than any others. This paper will, therefore, demonstrate the<br>analysis for two means of calculations.</p>}, number={2}, journal={NKRAFA JOURNAL OF SCIENCE AND TECHNOLOGY}, author={รัตนศีล ฤชา}, year={2020}, month={Dec.}, pages={74–80} }
