6. For the following matrix (you can generate it using: >> A = magic(4) A=[ 16 23 13 5 11 10 8 9 7 6 12 4 14 15 1] 6.1) what would be the element A[5) 6.2) what would be the element A(1,2) 6.3) What is the linear index and subscript for the element that is equal to 10 6.4) Delete the last column, and assign this new matrix, B1 Computer Apps 1 Practice Problem 2 Do the following manipulation: 6.5) Delete the first and second column and assign this new matrix, B2 6.6) Add an additional column (5th column that is vec[1:2; 3; 4). assign the new matrix B3 (size 4x5) 6.7) Add vec =[1:2; 3:4) between the column 1 and 2 of matrix A so that B4 = 16 1 2 3 13 5 2 11 10 8 9 3 7 6 12 4 4 14 15 1 1, 2, 3, 4); to the last row so that 6.8) In similar fashion, add a row vector, vec B5 = 16 2 3 13 5 11 10 8 9 7 6 12 4 14 15 1 1 2 3 4
