How to plot every column of matrix into a different graphic but in one figure

i have a matix 13 x 4, i want that first column get plot in one graph, then plot 2nd column in another graph, so on until the 4th column. but every graphs must be plot in one figure. can anyone give me the solution of it using loop or "for" function? thank you!

Answer 1

plot(matrix)

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

Ah i missed the part “different graphic” ;), figure(1) could be used before the loop.

thank you for you solution.

but what if I want the second graph stacked above of the first graph, then stacked the third graph above of them and then the 4th graph??

[madhan ravi]

Madania for that look at my solution .

[Aquatris]

If you want all columns in the same plot

plot(A)

would do the job.

Edit: basically what madhan ravi gave as an answer

And ofcourse the original question is answered by Aquatris without a doubt.

okay, this is good but I have very large array, and using for loop is taking time, how can we do it without for loops?

% 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.

[Madania Nia]

thank you for ur help. but, why it say "invalid expression" in plot part?

[madhan ravi]

plot(t,A(:,i)) % because he missed one “)” % at the end of that line

[Madania Nia]

ah i see, i didnt check it :D

thank you so much
