Undefined operator '<' for input arguments of type 'struct'.
Error in TrainAnfisUsingPSO>RunPSO (line 103)
if particle(i).Best.Cost<BestSol.Cost
CODE IS HERE:
empty_particle.Position=[];
empty_particle.Cost=[];
empty_particle.Velocity=[];
empty_particle.Best.Position=[];
empty_particle.Best.Cost=[];
particle=repmat(empty_particle,nPop,1);
BestSol.Cost=inf;
for i=1:nPop
% Initialize Position
if i>1
particle(i).Position=unifrnd(VarMin,VarMax,VarSize);
else
particle(i).Position=ones(VarSize);
end
% Initialize Velocity
particle(i).Velocity=zeros(VarSize);
% Evaluation
particle(i).Cost=CostFunction(particle(i).Position);
% Update Personal Best
particle(i).Best.Position=particle(i).Position;
particle(i).Best.Cost=particle(i).Cost;
% Update Global Best
var1=particle(i).Best.Cost;
var2=BestSol.Cost;
if particle(i).Best.Cost<BestSol.Cost %this line
BestSol=particle(i).Best;
end
end

Problem.CostFunction=@(x) TrainFISCost(x,fis,data);
CostFunction calls the following function:
function out=TrainFISCost(x,fis,data)
MinAbs=1e-5;
if any(abs(x)<MinAbs)
S=(abs(x)<MinAbs);
x(S)=MinAbs.*sign(x(S));
end
p0=GetFISParams(fis);
p=x.*p0;
fis=SetFISParams(fis,p);
