Question
sum(x')' Given the array A = [2 4 1;6 7 2;3 5 9], provide the commands needed to: Assign the element in first row and third column of A t a value of 10. Computer the sum of all the rows and columns. Compute the sum of column 2 only. Multiply A with 3 X 3 matrix of all ones. Compute the determinant of A. Given the arrays x = [l 4 8], y = [2 1 5] and A = [3 1 6;5 2 7], determine which of the following statement will correctly execute and provide the result. If the command will not correctly execute, state why it will not x + y x + A x' + y A - [x' y'] [x; y'] [x;y] A - 3 Create a 3 X 3 matrix 'B' random (1 to 100) and answer the following:Explanation / Answer
Activity 1.2
a) A=changem(A,[1],[10])
b)Sum(A) returns vector sum of all columns.
Sum(A,2)-vector contains sum of all rows
C)sum(A,1)
//compute the sum of column 2 only
d)let's assume b is a 3x3 matrix of all 1's.
Command is A*b
E. To compute determinant of A.
det(A)
Activity 1.3
a)x+y is valid gives[3,5,13]
b.)its an errorerror,they are of different sizes.
C)x'+y gives error.because they are different sizes.
D)A-[x'y'] subtracts product of x'y' from each element of A.
e)[x,y']
Conconatenates x and y'
F) concatenation of x and y
G.A-3.
subtracts all elements of A with 3.
