how to calculate the row space of a matrix in matlab

% Define a matrix A
A = [1 2 3; 4 5 6; 7 8 9];

% Compute the row-reduced echelon form of A
rrefA = rref(A);

% Find the indices of the pivot columns
ind = find(any(rrefA,2));

% Extract the corresponding rows from the original matrix
rowSpaceA = A(ind,:);

% Display the row space
disp("Row space of A:");
disp(rowSpaceA);
