Say I have a loop running how would I create a new variable that holds the columns I want say.
for ....
v= %some code that ouputs a 1 row 10 column data set say [1;2;3;4;5;...10]
x=v % x adds v as the first column.
% Then adds v again on the second loop run as the 2nd column then adds v again for the 3rd column
end
%so something like x=v, x=vv, x=vvv it keeps adding a new column to x of the data produced by v
I hope you can help. Thank you.

x = nan(10,num_loops);
for n = 1:num_loops
v = %some code that ouputs a 1 row 10 column data set say [1;2;3;4;5;...10]
x(:,n) = v; % x adds v as the first column.
end

x = zeros(10,3);
for i = 1:3
v = rand(10,1);
x(:,i) = v;
end
