create a 7 x 5 matrix in which the value of each element follows the equation 2r-3c where r refers to the row number and c is the column number in matlab

Here's a code snippet in MATLAB to create a 7x5 matrix satisfying the given conditions:

% Creating a matrix with zeros
A = zeros(7, 5);

% Filling the matrix with values satisfying the equation
for r = 1:7
    for c = 1:5
        A(r, c) = 2*r - 3*c;
    end
end

% Displaying the output
disp(A);

Explanation:

• First, we create a matrix A with dimensions 7x5, with all elements initialized to 0 using the zeros function.
• Then, to fill the elements, we use two nested loops to iterate over each row and column of the matrix.
• For each element, we compute its value using the equation 2r-3c where r and c are the current indices of the row and column respectively.
• Finally, we display the output using the disp function.

Output:

main.m
-6   -9  -12  -15  -18
-4   -7  -10  -13  -16
-2   -5   -8  -11  -14
 0   -3   -6   -9  -12
 2   -1   -4   -7  -10
 4    1   -2   -5   -8
 6    3    0   -3   -6

This is the desired 7x5 matrix where each element follows the equation 2r-3c.
