display the elements of a matrix a with elements form 1 to 100 that are divisible by 7 in matlab

You can use a combination of matrix iteration, conditional statements and modulo operator to display the elements of a matrix a with elements from 1 to 100 that are divisible by 7 in Matlab. Here's the code:

main.m
% Initialize the matrix
a = reshape(1:100, 10, 10);

% Iterate the matrix
for i = 1:size(a, 1)
    for j = 1:size(a, 2)
        % Check if the element is divisible by 7
        if mod(a(i, j), 7) == 0
            % Display the element
            disp(a(i, j))
        end
    end
end

In this code, we first initialize a matrix a with elements ranging from 1 to 100 using the reshape function. We then iterate through each element of the matrix using two nested for loops. For each element, we check if it is divisible by 7 using the mod function, which returns the remainder of a division. If the remainder is 0, it means that the element is divisible by 7, so we display it using the disp function.
