MATLAB: How to create a matrix of equal element value

matrix arraymatrix manipulation

If I want to create a 5 by 80 matrix of value 121 for each element, how can I do that? example A variable y is a 2 by 2 matrix of value 5 for each element is : y = [5,5;5,5]

Best Answer

y = 121*ones(5,80);

% If this is to be called iteratively
% Example while loop
iteration = 0;
while (iteration < numel(data)) % Some conditional to stay in your loop
    if ~iteration
        % Initially
        % A = [2.5 0; 0 2.4]; % Can you just initialize it with zeros?
        
        % Alternatively, suppose it was imported elsewhere:
        A = [ 2.5 0.25; ... % Top right = A(1,2);
              0.25 2.4];    % Bottom left = A(2,1);
        A = diag(diag(A)); % Keep only diagonal elements
    else
        A(1,2) = cov_ab; % Assume you get this from elsewhere
        A(2,1) = cov_ba;
    end 
    ...
    % Get covariance values 
    doc cov % May be helpful
    ...
    iteration = iteration + 1;
end
