create a 5 x 5 matrix a such that the values of the individual entries are the multplication of the row and column index. i.e. a(2,3) = 6 because (2)*(3) = 6 in matlab

To create a 5 x 5 matrix in MATLAB where the values of each entry are the multiplication of the row and column index, you can use a nested loop to iterate over the rows and columns, and calculate the product of the indices.

Here's an example code to create such a matrix:

main.m
% Define the size of the matrix
rows = 5;
columns = 5;

% Initialize the matrix with zeros
a = zeros(rows, columns);

% Populate the matrix with the product of the row and column indices
for i = 1:rows
    for j = 1:columns
        a(i,j) = i * j;
    end
end

% Display the resulting matrix
disp(a)

This code initializes a 5 x 5 matrix a with zeros, and then uses nested loops to calculate the product of the row and column indices, and assigns it to each entry in the matrix. Finally, the resulting matrix is displayed using the disp function.

The resulting matrix a would be:

main.m
  1   2   3   4   5
  2   4   6   8  10
  3   6   9  12  15
  4   8  12  16  20
  5  10  15  20  25

Each entry in the matrix a represents the product of its row and column indices. For example, a(2,3) is equal to 6 because 2 * 3 = 6.
