How Can I Manipulate Multiple Matrices at Once

I'm dealing with large number of matrices and I have to reshape them first and add all of them in a single matrix. To be clear: In my workspace there are 31X31 sized 50 matrices and named in an order " catal01, catal02, catal03...,catal50". Firstly I want to reshape all these matrices to 961X1 sized matrices. Any A matrix;

    A=catal01(:)

After completing making a single column process to all catalxx matrices I want to create a single matrix with these 50 columns. So ı will have 961X50 sized single matrix. I thought using for loop but cant succeed. How can I solve this problem?

i just started using MATLAB for couple of weeks ago. i will consider your comments. thanks.

They are not just my comments, but they are the combined comments of many code experts much better than you or I. You should consider them.

catal01=rand(10,1)
catal02=rand(10,1)
catal03=rand(10,1)
v=[]
for k=1:3
  a=evalin('base',sprintf('catal%0.2d',k))
  v=[v a]
end

it creates 31X1560 sized matrix, probably not as i wanted

[Azzi Abdelmalek]

Just adapt the code to your problem

v=[]
for k=1:3
a=evalin('base',sprintf('catal%0.2d',k))
v=[v a(:)]
end

You cannot manipulate multiple matrices at the same time.
