store vectors in matrix over for loop

Hi,

 How to store pairvec(in below code) variable in matrix overnested(ix1,ix2) loops. Pls help me in doing this.

Thanks, SIta

clc;
clear;
x1s=rand(3,1)
x2s=rand(3,1)
for ix1=1:3
  for ix2=1:3
      pairvec(:,:,ix1*ix2)= horzcat(x1s(ix1),x2s(ix2))
      temp=pairvec
  end
  %         finalvec=pairvec(ix1*ix2,:)
end

Answer 1

[Andrei Bobrov]

x1s=(1:3)';
x2s=(10:10:30)';

[ii jj]=ndgrid(x1s,x2s);

overnested = arrayfun(@(x,y)[x y],ii,jj,'un',0);

or

overnested2 = cat(3,ii,jj);

Thanks ...it is helpfull

Could you be more precise? Did you realize your pairvec is a 3D array, overnested(ix1,ix2) looks like a 2D array. Did you skip the semicolons (';') at the end of each line on purpose?

I am trying to store all combinations of x1s and x2s in pairvec here.I realize that is 3D array. Purposefully i skipped semicolons to observe output on command window .
