2-8-18 Matrix Calculations u Determinant [OPTN]-[MAT]-[Det] Example Obtain the determinant for the following matrix : Matrix A = 123 456 -1 -2 0 K2(MAT)3(Det)1(Mat) av(A)w u Matrix Transposition [OPTN]-[MAT]-[Trn] A matrix is transposed when its rows become columns and its columns become rows. Example To transpose the following matrix : Matrix A = 12 34 56 K2(MAT)4(Trn)1(Mat) av(A)w # Determinants can be obtained only for square matrices (same number of rows and columns). Trying to obtain a determinant for a matrix that is not square produces an error. # The determinant of a 2 × 2 matrix is calculated as shown below. |A| = a11 a12 a21 a22 = a11a22 - a12a21 # The determinant of a 3 × 3 matrix is calculated as shown below. |A| = a11 a12 a13 a21 a22 a23 a31 a32 a33 = a11a22a33 + a12a23a31 + a13a21a32 - a11a23a32 - a12a21a33 - a13a22a31 20050401
