The required details for MATLAB in given paragraph
The MATLAB language, a matrix-based language that enables the most natural expression of computer mathematics, is the core of MATLAB.
Here's one way to complete the task you described in MATLAB:
% Extract the first, second and third columns of the matrix s and store them in the variables s1, s2, and s3 respectively
s1 = s(:, 1);
s2 = s(:, 2);
s3 = s(:, 3);
% Compute the products r*s1, r*s2, r*s3 and store them in the variables c1, c2, c3 respectively
c1 = r .* s1;
c2 = r .* s2;
c3 = r .* s3;
% Build the matrix c with columns c1, c2 and c3
c = [c1 c2 c3];
The above code uses the colon operator (:) to extract the first, second, and third columns of the matrix s and store them in the variables s1, s2, and s3 respectively. Then it uses the element-wise multiplication operator (.) to compute the products rs1, rs2, rs3 and store them in the variables c1, c2, c3 respectively. Finally, it uses square bracket notation to concatenate the columns c1, c2, and c3 and store them in the matrix c.

You can use administrative units to delegate administrative tasks, such as creating and managing users, to specific users or groups.
By assigning User1 to an administrative unit that contains the users from the Marketing department only, you can ensure that User1 can manage only those users and not the users from the Human Resources department.

The program in Phyton that calculates the cost for replacing the carpet for a room. Carpet is priced by square foot. Total cost of carpet replacement includes carpet, labor and sales tax, where dollar values are output with two decimals is given as follow:
carpet_price_per_sqft = float(input("Enter the price of the carpet per square foot: "))
room_length = float(input("Enter the length of the room: "))
room_width = float(input("Enter the width of the room: "))
labor_cost = float(input("Enter the labor cost: "))
sales_tax_rate = float(input("Enter the sales tax rate (as a decimal): "))
# Calculate the area of the room
room_area = room_length * room_width
# Calculate the cost of the carpet
carpet_cost = room_area * carpet_price_per_sqft
# Calculate the total cost, including labor and sales tax
total_cost = carpet_cost + labor_cost
sales_tax = total_cost * sales_tax_rate
total_cost += sales_tax
# Output the total cost with two decimal places

1-21. internally in a computer, with few exceptions, all computation is done using binary numbers. output, however, often uses ascii, which is formed by appending 011 to the left of a bcd code. thus, an algorithm that directly converts a binary integer to a bcd integer is very useful. here is one such algorithm: draw lines to bound the expected bcd decades to the left of the binary number. move the binary number one bit to the left. add 0011 to each bcd decade containing a binary value > 0100. repeat steps 2 and 3 until the last bit in the binary number has been moved into the least significant bcd decade position. read the bcd result. execute the algorithm for the binary number 1111000. execute the algorithm for the binary number 01110010111.
A class of binary encodings of decimal numbers called binary-coded decimal (BCD) is used in electronic and computing systems. In BCD, each digit is represented by a fixed number.
What algorithm should be used for the binary number 01110010111?As is the case with all positional numeral systems, the base of the decimal system—also known as base-ten—is ten, which is written 10 in decimal. It is the numerical base that modern civilizations use the most.

Binary- coded decimal :A method of writing numbers that uses a four-digit binary code for each digit from 0 to 9 in a decimal (base 10) number is called binary-coded decimal. A method for converting decimal numbers into their binary equivalents is known as binary-coded decimal. A class of binary encodings of decimal numbers called binary-coded decimal uses four or eight bits to represent each digit. For a sign or other indication, special bit patterns may be utilized from time to time.
