[am1, am2, ..., amn] ] ... ... ... am1 am2 ... amn → Mat [letter A through Z] Example To input the following data as Matrix A: b,d,f c,e,g aK2(MAT) 1(Mat)av(A) w 1 3 5 2 4 6 • The maximum value of both m and n is 999. • An error occurs if memory becomes full as you are inputting data. • You can also use the above format inside a program that inputs matrix data. u To input an identity matrix Use the Identity command to create an identity matrix. Example To create a 3 × 3 identity matrix as Matrix A K2(MAT)6(g)1(Identity) da6(g)1(Mat)av(A)w Number of rows/columns [OPTN]-[MAT]-[Identity] 2-49
