how can I write all for loop outputs in single matrix?

how can I write all for loop results in single matrix?

For example

ans =
    -2    -2    -1
    -2    -2     1
    -2     2    -1
    -2     2     1
     2    -2    -1
     2    -2     1
     2     2    -1
     2     2     1
ans =
     0     0    -3
     0     0     3

I want to get a result such as

ans =
    -2    -2    -1
    -2    -2     1
    -2     2    -1
    -2     2     1
     2    -2    -1
     2    -2     1
     2     2    -1
     2     2     1
     0     0    -3
     0     0     3

For vertical concatenation

A=[1 2 3;4 5 6;7 8 9]
B=[10 20 30;40 50 60]
out=[A;B]

ok, but here all my outputs equal to just one parameter... for example what if for loop give two result such as

A=[1 2 3;4 5 6;7 8 9] A=[10 20 30;40 50 60]

maybe it is very basic but sorry I am very new

[Azzi Abdelmalek]

When you write

A=[1 2 3;4 5 6;7 8 9]
A=[10 20 30;40 50 60]

The first A will be erased by the second A, If you want to avoid this:

A=[1 2 3;4 5 6;7 8 9];
B=A;
A=[10 20 30;40 50 60];
out=[B;A]

sory I think I couldnot explain properly... For example I have a for loop

for i=1:size(a)
 % a&b two matrices and their dimensions are different
s = bsxfun(@times,a,b);
v=unique(s,'rows')
end

therefore, my outputs equal to same parameter "v"

What is the problem with your previous comment?

Hi,

Thought I would jump in as I'm having the same difficultly. The loop produces say 21 results, all labelled 'A'. Vertical concatination would work, but as all outputs are produced at once, it's not possible (or practical) to label each output with an alternative letter.

TIA

Try this construct

out = [];
for jj = ...
    % here your execution
    A = ...
    out = [out;A];
end

Hi,

Sorry I'm very new to MATLAB, please could you explain a little more? I can't seem to use the above to 'join' all the loop results in a single matrix.

TIA
