This might be what you are looking for
A = rand(13,4); % random 13x4 matrix
[r,c] = size(A); % get number of rows and columns of A
for i = 1:c % columns 1 to c
figure(1)
subplot(c,1,i),plot(A(:,i)) % plot the ith column in ith graph in figure(1)
%subplot(1,c,i),plot(A(:,i)) % alternative for horizontal layout
end

If you want all columns in the same plot
plot(A)
would do the job.
Edit: basically what madhan ravi gave as an answer

% let us suppose your matrix is A,and you want toplot all the columns of A with espect to dome other variable. You havent mentioned that variable in the question. i am considering it as ' t ' .
the code will be as follows.
clc
clear all
A=[] % your matrix.
t=[] % the x axis variable. it should have same number of elements as of the elements in one column of A ie 13.
for i=1:4
plot(t,A(:,i)
hold on
end
% this code will work. message here if you find any difficulty. Give me a up thumb if this helps to you. Thanks.
