Add a command for unique permutations

At this moment I have function which creates a matrix of n rows and Nvar columns. I want to add to the if-line that each permutation should be unique.

E.g. when I enter InitialPopulation(60,3); I get a lot of the same permutations but I want him to make a list of the unique ones.

This is my code:

function InitPop = InitialPopulation(n,Nvar)

InitPop = zeros(n, Nvar);

for index = 1:n

test = 0;

while test ~= 1

test = 0;

InitPop(index,:) = randperm(Nvar);

%random permutations of the vertices

if InitPop(index, 1) == 1

test = 1;

%making sure that the permutation starts with the first vertex

end

end

end

end

[JESUS DAVID ARIZA ROYETH]

you can make

list = unique (InitialPopulation (60,3), 'rows')

but it would no longer be 60 in size

On the other hand if you want to get all the permutations you can simply do:

perms (1: 3)

Thanks, It worked :)
