How ca I calculate the dominance between two popultion?

Hello every one ,

I have a problem and I want to solve it, so

I have two population pop and Pool type struct

pop: Position []

Cost []

Pool:

pop has value in both field

example

pop(1): [123, 0 , 1000, 52, 54, 200]

[0 4 0 210]

note Cost has always 4 values

and the size of Position is fixed (100)

I want to compare each line from pop with Pool by using Dominance concept

at the first time Pool is empty

for s=1:N

if ~isempty(Pool)

for c=1:numel(Pool)

if ~Dominates(pop(s),Pool(c))

pop(s).IsDominated=true;

Pool(c)=[];

Pool=[Pool pop(s)];

end

end

else

Pool=[Pool pop(s)];

end

end

I try this code but ir doesn't work, an arror appear

Error using <=

Matrix dimensions must agree.

Error in Dominates (line 24)

b=all(x<=y) && any(x<y);

The dominates function is as follow:

function b=Dominates(x,y)

if isstruct(x)

x=x.Cost;

end

if isstruct(y)

y=y.Cost;

end

b=all(x<=y) && any(x<y);

end

Please help me

THank you.
