2-8-17 Matrix Calculations u Matrix Arithmetic Operations [OPTN]-[MAT]-[Mat]/[Iden] Example 1 To add the following two matrices (Matrix A + Matrix B) : 11 A = 21 23 B = 21 AK2(MAT)1(Mat)av(A)+ 1(Mat)al(B)w Example 2 Calculate the product to the following matrix using a multiplier value of 5 : 12 Matrix A = 34 AfK2(MAT)1(Mat) av(A)w Example 3 To multiply the two matrices in Example 1 (Matrix A × Matrix B) AK2(MAT)1(Mat)av(A)* 1(Mat)al(B)w Example 4 To multiply Matrix A (from Example 1) by a 2 × 2 identity matrix AK2(MAT)1(Mat)av(A)* 6(g)1(Iden)cw Number of rows and columns # The two matrices must have the same dimensions in order to be added or subtracted. An error occurs if you try to add or subtract matrices of different dimensions. # For multiplication (Matrix 1 × Matrix 2), the number of columns in Matrix 1 must match the number of rows in Matrix 2. Otherwise, an error occurs. # When performing matrix arithmetic operations, inputting the Identity command at the location of a matrix command (such as Mat A) makes it possible to perform identity matrix calculations. 20050401
