Please I need help creating a matrix containing all possible combinations of the elements of the following vectors: The order matters and elements are unique.
cf = [4.35e-09 7.25e-09 1.015e-08 ];
phif = [0.002 0.02 0.2];
kf0 = [ 4e-14 8e-14 1e-13];
xF = [100 120 150 180];
cm = [3.25e-10 7.25e-10];
cF = [4.35e-09 7.25e-09 1.015e-08];
Le = 880;
nHF = [8 : 1: 12];
ye = [(Le./nHF)./2];
yc = [0.4.*ye 0.6.*ye 0.8.*ye];
phim = [0.12 0.3];
kF0 = [5e-11 1e-10 1.5e-10];
kminfty = [1e-18 1e-19];
phiF = [0.002 0.02];
My objective at each STEP is:
var(i:number_of_possible_combinations) = [cf phif kf0 xF cm cF ye yc phim kF0 kminfty phiF ];

Download Jos's excellent FEX submission allcomb, which does exactly what you want. I leave it up to you to decide if your computer has enough memory, and you have enough time to wait for this to be calculated.

Use concatenation function to create matrix using several vectors.

I'm trying to perform a combination so I'll have a whole lot of possible combinations not just a single matrix. I want to pick the first element of a vector and combine it with the first element of the other vectors and then the second etc..

see combvec():
matrix = combvec(cf, phif, kf0, xF, cm, cF, ye, yc, phim, kF0, kminfty, phiF);
