Creating 25 x 2 matrix with each row range is 20

i want to occupy 1 to 500 in a matrix of size 25x2 with range of each row is 20. First row contains [1 20], second row contains [21 40], and so on until last 25th row containing [481 500]. I asked chat GPT. It suggested me the following code. But it did not go well.

% Define the range and matrix size
range = 1:500;
matrix_size = [25, 2];

% Calculate the values for each row
row_values = reshape(range, [], 20)';

% Create the matrix by repeating the row values
matrix = repmat(row_values(:), 1, matrix_size(2));

% Reshape the matrix to the desired size
matrix = reshape(matrix, matrix_size);

% Display the matrix
disp(matrix);

Pls clarify!

m = (0:20:499).' + [1,20]

m = 25×2

1 20 21 40 41 60 61 80 81 100 101 120 121 140 141 160 161 180 181 200
