%列状数据升序排列

% A=[11 4 0.2;22 3 0.5;0 3 0.4];
% sort(A)
%
%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).
%
% 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];
