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]

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
