How to make a matrix from several column vectors

Hi, Can anybody help me with this? I have 30 column vectors: norm(:,1,stn), where stn = 1:30. How do I put these 30 column vectors into one matrix? So that I get

a = [norm(:,1,1) norm(:,1,2) norm(:,1,3) etc.] ???

Thanks!

Answer 1

[Azzi Abdelmalek]

m=size(norm,1);
a=zeros(m,30);
for k=1:30
  a(:,k)=norm(:,1,k);
end

%or

a=reshape(norm(:,1,1:30),[],30)

When you say "into one matrix" do you want a two dimensional matrix as Azzi proposed? If you want one long vector as the line

a = [norm(:,1,1) norm(:,1,2) norm(:,1,3) etc.]

indicates you can actually just type

a=norm(:);

Since matlab will allways read columnwize.This will produce a column vector. If you want a row vector instead type

a=norm(:).';

If you want a 2D matrix you can also use this method but then you need to pre allocate a zero matrix.

m=size(norm,1);
a=zeros(m,30);
a(:)=norm(:);

norm1 = randi(10,5,1,30); % Let

a = squeeze(norm1);
