find the Unique Coupled-value in a vector and eliminate the zero-coupled values

Hello everybody,

Thank you for the interest for my question and your help I am not successful to find an algorithm which permits to get unique coupled-values in a two-rows vector. Here is the example:

vect=[
1   599   256   599   256   0   0  0  0  0 324 599 256 256 599
171 171   150   171   150 150 171  0  0  0 171 150   0 171 150 
]

The results that I want is

res=
    [
    1   599   256   0   0  324 599 256 256 
    171 171   150 150 171  171 150   0 171 
    ]

Could you please provide an algorithm for me ?

Thanks in advance,

gringoire lee

[a b c] =unique(vect','rows','first')
out = sortrows([a,b],3)
res = out(any(out(:,1:2),2),1:2)'

thanks... this is exactly I want
