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];
