Answer:

Complete Matalb code along with explanation and output results are given below

Explanation:

We are given following two matrices A and B of size 4x3

A = [1 4 2; 2 4 100; 7 9 7; 3 pi 42]

B = log(A)

(a) Select just the second row of B

% to extract any row use this syntax B(row no, : ) we can also extract more than 1 row or any particular elements in a specific row

B_row_2 = B(2,:)

(b) Evaluate the sum of the second row of B

% simply use the sum function and pass it any vector or matrix and it will return their sum

sum_B_row_2 = sum( B_row_2(:) )

(c) Multiply the second column of B and the first column of A element by element

% first we extract the column 2 of matrix B and column 1 of matrix A. use this syntax B( : ,col no ) to extract any column

B_col_2 = B(:,2)

A_col_1 = A(:,1)

% Then we use ( .*) to multiply element by element. To use standard multiplication of matrices only use asterisk sign without coma

multiply=B_col_2.*A_col_1

(d) Evaluate the maximum value in the vector resulting from element-by- element multiplication of the second column of B with the first column of A

% we can find the maximum value in a vector or matrix by using max function so we pass the multiply variable where our result was stored

max_value = max(multiply)

(e) Use element-by-element division to divide the first row of A by the first three elements of the third column of B. Evaluate the sum of the elements of the resulting vector

% First we extract the row 1 of matrix A

A_row_1 = A(1,:)

% Then we extract the column 3 of matrix B

B_col_3 = B(:,3)

% Then we extract the first 3 elements of column 3 of matrix B

B_col_3 = B_col_3(1:3)

% Finally we use ( ./ ) to use element by element division

divide = A_row_1./B_col_3

% Using the sum function again results in the addition of entire elements of resultant matrix

sum_divide = sum( divide(:) )

Only Code:

A = [1 4 2; 2 4 100; 7 9 7; 3 pi 42]

B = log(A)

B_row_2 = B(2,:)

sum_B_row_2 = sum( B_row_2(:) )

B_col_2 = B(:,2)

A_col_1 = A(:,1)

multiply=B_col_2.*A_col_1

max_value = max(multiply)

A_row_1 = A(1,:)

B_col_3 = B(:,3)

B_col_3 = B_col_3(1:3)

divide = A_row_1./B_col_3

sum_divide = sum( divide(:) )

Output Results:

A =

2.0000 4.0000 100.0000

Why linked list is better than an array?

katrin [286]

In conclusion there are many different data structures. Each data structure has strengths and weaknesses which affect performance depending on the task. Today, we explored two data structures: arrays and linked lists. Arrays allow random access and require less memory per element (do not need space for pointers) while lacking efficiency for insertion/deletion operations and memory allocation. On the contrary, linked lists are dynamic and have faster insertion/deletion time complexities. However, linked list have a slower search time and pointers require additional memory per element in the list. Figure 10 below summarizes the strength and weakness of arrays and linked lists.

Justify the need for branching and jump codes in the instruction set using real world scenarios

topjm [15]

Answer:

As in the real world, people using a program would provide different inputs, that would require different outputs. For example in a traffic light system, there could be a function that constantly checks for if the button is pressed. When the button is pressed the traffic light loop would branch out of its current running code in order to turn the lights to red, and allow the pedestrians to cross.
