Hi,
I am getting a parameter called 'test' in a for loop. I want to write it to a matrix or array without overwriting. Each loop has a different dimension so that makes it a bit complicated.
I need on line h 'r' values of test, line h the new 'r' values of test and so on. So test needs to come in row h, column r.
for h = 3:10
...
...
...
A = []
for r = 1:g
...
for m = 1:numbcenterlines
...
percentage(m) = sum(distance>0 & distance <1) / numel(distance)*100;
test = max(percentage,[],'all');
end
A(r,h) = [A;test] %this part doesn't work well so my question is how to fix this part and get an array here with all the test values without overwriting
end
end

You are mixing up two different approaches to adding data in a loop: concatenation and indexing. Just pick one, e.g.:
A = [A;test];

A =
0 0 67.9666
0 0 57.2263
0 0 73.3220
0 0 19.6101
0 0 21.3058
0 0 88.3791
0 0 78.7196
A =
0 0 0 36.5854
0 0 0 36.5854
0 0 0 36.5854
0 0 0 36.5854
0 0 0 36.5854
0 0 0 36.5854
0 0 0 36.5854
This is the result, but i want to save the third column aswell.
