help sort

 SORT   Sort in ascending order.
    For vectors, SORT(X) sorts the elements of X in ascending order.
    For matrices, SORT(X) sorts each column of X in ascending order.
    For N-D arrays, SORT(X) sorts the along the first non-singleton
    dimension of X. When X is a cell array of strings, SORT(X) sorts
    the strings in ASCII dictionary order.
 
    SORT(X,DIM) sorts along the dimension DIM.
 
    [Y,I] = SORT(X) also returns an index matrix I. If X is a
    vector, then Y = X(I).  If X is an m-by-n matrix, then
        for j = 1:n, Y(:,j) = X(I(:,j),j); end
 
    When X is complex, the elements are sorted by ABS(X).  Complex
    matches are further sorted by ANGLE(X).
 
    When more than one element has the same value, the order of the
    elements are preserved in the sorted result and the indexes of
    equal elements will be ascending in any index matrix.
 
    Example: If X = [3 7 5
                     0 4 2]
 
    then sort(X,1) is [0 4 2  and sort(X,2) is [3 5 7
                       3 7 5]                   0 2 4];
