Matrix formed by Vectors?Easy question.

I have a matrix size=10x10. And I want to obtain each column as a vector. Or vectors will create a matrix. How can I do that? Thanks in advance.

Answer 1

Yup, simple:

M  =randn(10);
for i1 = 1:size(M;2)
  V{i1} = M(:,i1);
end

Then you have your vectors in the cells of V.

The other direction:

M = [v1,v2,v3,....,vN];

There vN has to be column vectors.

v=[1 2 3;4 5 6;7 8 9]
v1=v(:,1) % first column
v2=v(:,2)
v3=v(:,3)

% horizontal concatenation

v=[v1 v2 v3]
