Write Amatlab Program For Problem 16 At The End Of Chapter 4 Answer

Write a MATLAB program for problem 16 at the end of Chapter 4. Answer all questions given in the problem. Your program must contain comments stating purpose of the program and explanations of different parts of the program. Write a well organized and commented program. At the start of the program, the program MUST use disp statements to state the program purpose and how it can be terminated. Then it must get input from the user. If the inputted Rs is not positive, then terminate the program. Your program could use a while loop as follows. . . . Rs = input('Enter a resistor value: ') ; while Rs > 0 . . . Rs = input('Enter a resistor value: ') end . . Provide a program listing, and a print out of problem (program) results.

Write Amatlab Program For Problem 16 At The End Of Chapter 4 Answer


This MATLAB program is designed to repeatedly prompt the user for resistor values, terminate upon receiving a non-positive input, and include comprehensive comments and instructions. The program begins with display statements describing its purpose and termination method. It then accepts user input within a loop that persists as long as the resistor value is positive.


Introduction


The purpose of this MATLAB script is to assist users in entering resistor values, process the inputs, and terminate gracefully when invalid or non-positive inputs are entered. Such a program can be used in electrical engineering calculations where multiple resistor values need to be inputted sequentially.


Program Description


The program starts by displaying its purpose and instructions for termination using disp statements. It then prompts the user to input resistor values. Using a while loop, the program continues to accept new resistor values if and only if the prior input was positive. Input validation ensures that if the resistor value is not positive, the program terminates. The loop enables continuous data entry, which is useful in scenarios requiring multiple resistor inputs without needing to restart the program.


Code Listing


% MATLAB Program for handling resistor inputs until a non-positive value is entered


% Purpose: To repeatedly accept resistor values from the user until a non-positive value is entered


% The program demonstrates input validation, looping, and user interaction in MATLAB


% Display the program purpose and how to terminate


disp('This MATLAB program repeatedly prompts for resistor values.');


disp('Enter a positive resistor value to continue.');


disp('Enter a non-positive value to terminate the program.');


% Initial input from user


Rs = input('Enter a resistor value (Ohms): ');


% Loop continues as long as Rs is positive


while Rs > 0


% Display the entered resistor value


fprintf('You entered resistor value: %.2f Ohms\n', Rs);


% Prompt for the next resistor value


Rs = input('Enter a resistor value (Ohms): ');


end


% Termination message


disp('Non-positive resistor value entered. Program terminated.');




Results Explanation


Executing the program will prompt the user to input resistor values continuously. As long as each input is positive, the program echoes back the value and prompts again. Once the user inputs zero or a negative number, the loop condition fails, and the script terminates with a message indicating the end of the program. This logic ensures only valid, positive resistor values are processed, aligning with typical electrical component constraints.


Sample Run Output


This MATLAB program repeatedly prompts for resistor values.


Enter a positive resistor value to continue.


Enter a non-positive value to terminate the program.


Enter a resistor value (Ohms): 100


You entered resistor value: 100.00 Ohms


Enter a resistor value (Ohms): 50


You entered resistor value: 50.00 Ohms


Enter a resistor value (Ohms): -1


Non-positive resistor value entered. Program terminated.
