Answer:

Explanation:

The Matlab Function rowproduct.m

function C = rowproduct( A,B) % The function rowproduct.m

M = size(A); % Getting the dimension of matrix A

N = size(B); % Getting the dimension of matrix B

if(M(2)~=N(1)) % Checking the dimension

fprintf('Error in matrix dimension\n'); % print error if dimension mismatch

return; % And end the further execution of function

end % End of if condition

C = []; % initilizing the result matrix C

for k = 1:M(1) % Loop to perform the row product

C = [C;A(k,:)*B];% Computing row product and updating matrix C

end % End of loop

end % End of function

Testing the function rowproduct.m

The 2x3, 3x2 Matrix:

>> A = [ 1 2 3; 1 2 3];

>> B = [1 2; 1 2; 1 2];

>> C = rowproduct(A,B)

C =

6 12

6 12

>> A*B

ans =

6 12

6 12

The 3x4, 4x2 matrix:

>> A = [ 1 2 3 4; 1 2 3 4; 1 2 3 4];

>> B = [1 2; 1 2; 1 2; 1 2];

>> C = rowproduct(A,B)

C =

10 20

10 20

10 20

>> A*B

ans =

10 20

10 20

10 20

The 3x4 and 2x4 matrix:

>> A = [ 1 2 3 4; 1 2 3 4; 1 2 3 4];

>> B = [1 2 1 2; 1 2 1 2];

>> rowproduct(A,B)

Error in matrix dimension

Write a java program that would request user name, id number, and state the time the user has reported at work.​
Troyanec [42]

Answer:

import java.text.DateFormat;

import java.text.SimpleDateFormat;

import java.time.LocalDateTime;

import java.time.format.DateTimeFormatter;

import java.util.Date;

import java.util.Scanner;  

public class Main {

   private static final DateFormat dateformat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");

   private static final DateTimeFormatter datetimeformat = DateTimeFormatter.ofPattern("yyyy/MM/dd HH:mm:ss");

   public static void main(String[] args) {

       

       System.out.println("Enter your ID and Name");

       LocalDateTime current = LocalDateTime.now();

       Scanner sc1 = new Scanner(System.in);  

       String Name= sc1.nextLine();

       int ID = sc1.nextInt();

       System.out.println(Name + "reported at:");

      System.out.println(datetimeformat.format(current));

   }

}

Explanation:

The above program saves the current date-time as well, at the time when the user enters his name and ID. And it prints the same on the screen. Further, you can store these in a data structure like list or class or you can store it in a database as well. Remember, this is the difference between a program and a web application, and not to forget we have a toolkit in case of the web application. And here we are working on the console. Also, a web application has a front panel and back panel. However, a program only solves a computing problem, and there is no well-designed interface with the user. However, programming is the root of all other programmings like web programming, mobile app programming, etc.

Rashid [163]

Answer:

The correct answer is B. This is unacceptable because Brad is not registered in State B

Explanation:

Given:

Brad is a registered Investment Advisory Representative (IAR) in State A.

In the question, it's not stated that Brad is not registered in State B.

Setting up an office in State B is unacceptable because Brad is holding himself out as an IAR in State B and he is not registered as an IAR in State B.

Though GHI is a registered firm in State B, Brad also needs to be registered before setting up an office in other states.
