Thank you for your kind reply, Alan!
I modified my code in this way:


gs = GlobalSearch;
G1 = (x0(1)*((-96.19)+ log((x0(1))/(sum(x0)))))+(x0(2)*((-103.5765)+ log((x0(2))/(sum(x0)))))+(x0(3)*((-60.7612)+ log((x0(3))/(sum(x0)))))+(x0(4)*((-157.2666)+ log((x0(4))/(sum(x0)))))+(x0(5)*((-15.7762)+ log((x0(5))/(sum(x0)))))+(x0(6)*((-93.7912)+ log((x0(6))/(sum(x0)))))+(x0(7)*((-152.1869784261)+ log((x0(7))/(sum(x0)))))...
    +(x0(8)*((-65.1308)+ log((x0(8))/(sum(x0)))))+(x0(9)*((-156.5081915685)+ log((x0(9))/(sum(x0)))));
options = optimset('Algorithm','interior-point','MaxFunEvals',1000000,'MaxIter',10000000,'TolCon',1e-12);
problem = createOptimProblem('fmincon','x0',[+1e-4,+1e-4,+1e-4,+1e-4,+1e-4,+1e-4,+1e-4,+1e-4,+1e-4],...
    'objective',G1,'lb',[0 0 0 0 0 0 0 0 0],'Aeq',[1 1 1 2 0 1 2 1 2;4 2 0 0 2 6 4 2 2;1 0 1 1 0 2 2 1 1],'beq',[1;4;1],'options',options);
[xmin,fmin,flag,outpt,allmins] = run(gs,problem);
xmin;
fmin;

but I still get an error as an output:
"Undefined function 'x0' for input arguments of type 'double'.".
I found this type of error depends usually on a wrong choose of directory, but this is not the case.
What could be an other reason?
Thank you again!
