Question
Q1 // You are given a matrixu = [2;1;1;1) , in Matlab and a second matrix v =
(0.5;1;0;0). We now perform the matrix- by - matrix product " u times vT ", w =
u(vT) . (1) ,where recall that Tdenotes transpose.
(choose 10 only)
1- The size of the matrix w is
А. 1х 1
В. 1 х 4
C. 4x 4
D. 4 x1
2- The operation of equation (1) is implemented in Matlab as
A. W=u.*v
B. w = v.*u
C. w =u*v
D. w =u*v
3- The value of w(1,1) is
A. 0.5
В. 1.0
С. 2.5
D. 2.0
4- The size of the matrix u is
А. 1 х 1
В. 1 х4
C. 4x4
С. 4х4
D. 4 x 1
We now perform the matrix - by - matrix product " uT times v", z = (uT)v .. (2),
where again T denotes transpose.
5- The size of the matrix z is
А. 1 х1
В. 1 х4
C. 4x 4
D. 4 x 1
6- The operation of equation (2) isimplemented in Matlab as
A. 2= u.*v
B. z= v.*u
C. z= u*v
D. 2= u*v
7- The value of z(1,1) is
A. 0.5
В. 1.0
C. 2.5
D. 2.0
8- what's we can use another named for u ?
9- find the result of operation " u+v"
10 - find the max value of v ?
11- find the min value of u ?
