Question
The following matrices M and N are given: 3 7-4121 M=1-5 9 10 2 2 N= 6 13 8 11 6 -2 15 5 4 Determine the product of Matrix M and Matrix N. Store the product in Matrix AA. Use the appropriate Matlab function(s) to sort each row of the matrix M in ascending order save it in matrix BB b. c. Without re-entering any values creat the matrix E containing columns 1 and 4 of matrix M d. Perform an element by element multiplication of N by E. Store the results in matrix F. e. Append matrix E to matrix N to form a 4 x 4 matrix called G Find the cubic value of each element in Matrix M. Call the resulting matrix AAAExplanation / Answer
The following matrices M and N are given below as :
M = [ 3 7 -4 12 ]
[ -5 9 10 2 ]
[ 6 13 8 11 ]
[ 15 5 4 1 ]
N = [ 4 -2 ]
[ 5 3 ]
[ 6 -2 ]
[ 7 4 ]
(1) Determine the product of Matrix M and Matrix N. Store the product in Matrix AA.
Matrix AA = (Matrix M) x (Matric N)
Matrix AA = [ 3 7 -4 12 ] x [ 4 -2 ]
[ -5 9 10 2 ] x [ 5 3 ]
[ 6 13 8 11 ] x [ 6 -2 ]
[ 15 5 4 1 ] x [ 7 4 ]
Matrix AA = [ (12 + 35 - 24 + 84) (-6 + 21 + 8 + 48) ]
[ (-20 + 45 + 60 + 14) (10 + 27 - 20 + 8) ]
[ (24 + 65 + 48 + 77) (-12 + 39 - 16 + 44)]
[ (60 + 25 + 24 + 7) (-30 + 15 - 8 + 4) ]
Matrix AA = [ 107 71 ]
[ 99 25 ]
[ 214 55 ]
[ 116 -19 ]
(f) Find the cubic value of each element in Matrix M. Call the resulting matric AAA.
Matrix AAA = (Matrix M) x (Matrix AA)
Matrix AAA = [ 3 7 -4 12 ] x [ 107 71 ]
[ -5 9 10 2 ] x [ 99 25 ]
[ 6 13 8 11 ] x [ 214 55 ]
[ 15 5 4 1 ] x [ 116 -19 ]
Matrix AAA = [ (321 + 693 - 856 + 1392) (213 + 175 - 220 - 228) ]
[ (-495 + 891 + 2140 + 232) (-355 + 225 + 550 - 38) ]
[ (642 + 1287 + 1712 + 1276) (426 + 325 + 440 - 209) ]
[ (1605 + 495 + 856 + 116) (1065 + 125 + 220 - 19) ]
Matrix AAA = [ 1550 -60 ]
[ 2768 382 ]
[ 4917 982 ]
[ 3072 1391 ]
