[~,idx]=sort(matrix);
matrix(idx,:) % first column sorted in ascending order if vice versa use 'descend' option

Not sure what you mean, perhaps it would be better off if you start a new question with all the necessary illustrations.

What does ~ mean? What does idx mean? What does : mean?
The answers is very convoluted and not generalizable.
How do i, in easy terms, sort A and B column vectors by A column, descending in values?
