sorted_M = Matrices.sort(M); (sorted_M, indices) = Matrices.sort(M, sortRows=true, ascending=true);
Function sort(..) sorts the rows of a Real matrix M in ascending order and returns the result in sorted_M. If the optional argument "sortRows" is false, the columns of the matrix are sorted. If the optional argument "ascending" is false, the rows or columns are sorted in descending order. In the optional second output argument, the indices of the sorted rows or columns with respect to the original matrix are given, such that
sorted_M = if sortedRow then M[indices,:] else M[:,indices];
(M2, i2) := Matrices.sort([2, 1, 0; 2, 0, -1]); -> M2 = [2, 0, -1; 2, 1, 0 ]; i2 = {2,1};
