Hi all, so I have a Matrix A (270,10) and I want to create, for each column, a different vector, caled for example b1, b2, b3 and so forth...
so here I have the code:
notes: size(varargout,2) = 270
for h = 1: size(varargout,2)
for v=1:10
vectors = A(:,v);
end
end
it keeps giving me matrixes, when I wanted separated vectors...
Can anyone help me?
Thanks!!

"...caled for example b1, b2, b3 and so forth..."
Using numbered varaibles is a sign that you are doing something wrong.
It is much simpler and much more efficient to use indexing.

What you're doing is not a good idea see https://in.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval , use a cell array or a ND array instead.
b=num2cell(matrix,1);
celldisp(b)
