matlab ones

In MATLAB, the function ones is used to create an array filled with ones. Here's a quick guide and example:

Syntax:

ones(m, n)  % Creates an m x n matrix of ones
ones(m)     % Creates a 1 x m row vector of ones
ones(n)     % Creates a n x 1 column vector of ones
ones(m, n, k) % Creates an m x n x k 3D array of ones

Example:

% Create a 3x4 matrix of ones
A = ones(3, 4);
disp(A);

% Create a 1x5 row vector of ones
B = ones(1, 5);
disp(B);

% Create a 5x1 column vector of ones
C = ones(5);
disp(C);

% Create a 2x2x2 3D array of ones
D = ones(2, 2, 2);
disp(D);

Output:

1 1 1 1
1 1 1 1
1 1 1 1

1 1 1 1
1 1 1 1

1 1 1 1 1
1 1 1 1 1

1 1 1 1 1
1 1 1 1 1
1 1 1 1 1
1 1 1 1 1

Let me know if you want to create a custom size or use it in a specific context!
