M=rand(4,3)
% std for each row
s1=std(M,[],2)
% std for each column
s2=std(M)

mean(M,2),
median(M,2)

Such questions are solved exhaustively in the documentation of Matlab: see doc std.
If you do not know the required command, you can look in the "See also" line of similar commands or use docsearch to search for terms inside the documentation. Even asking your favorite internet search engine is a good idea. All of these ideas are faster and more efficient than asking the forum, so it is recommended to try them at first.
