Sorting elements in a matrix via first column characterization

I'd like to know if there's a way to sort rows of a matrix by the entries in the first column.

For example, if I have a matrix

A = [9 4 5; 3 3 1; 5 8 4;]

I want to do something like "B = sort(A)" and have MATLAB return:

B = [3 3 1; 5 8 4; 9 4 5;]

Where all rows are sorted based on the first entry. Thanks.

B = sortrows(A,1);

or

[~,ii] = sort(A(:,1));
B = A(ii,:);
