hello everyone i have problem with this error in genetic algorithm(Invalid value for OPTIONS parameter PopInitRange: must be an array of finite doubles with two rows)

the code is

%To minimize our fitness function using the ga function, we need to pass in a function handle to the fitness function as well as specifying the number of variables as the second argument. Lower and upper bounds are provided as LB and UB respectively. In addition, we also need to pass in a function handle to the nonlinear constraint function.
   ObjectiveFunction = @simple_fitness;
   nvars = 14;              % Number of variables
    LB = [0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1]; % Lower bound for (x1 x2 x3 x4 x5 x6 x7 x8 x9 x10 x11 x12 x13 x14)
    UB = [1.1 1.1 1.1 1.1 1.1 1.1 1.1 1.1 1.1 1.1 1.1 1.1 1.1 1.1]; % Upper bound for (x1 x2 x3 x4 x5 x6 x7 x8 x9 x10 x11 x12 x13 x14)

    options= gaoptimset(options,'Tolfun',1e-4,'TolCon',1e-3,'stallGenlimit',1000);
    options= gaoptimset(options,'paretoFraction',0.5);
    options=gaoptimset(options,'PopInitRang',[0.1 ; 1.1;0.1 ; 1.1;0.1 ;1.1;0.1 ;1.1;0.1 ; 1.1;0.1 ; 1.1;0.1 ; 1.1;0.1 ;1.1;0.1 ; 1.1;0.1 ; 1.1]);
    options=gaoptimset(options,'PopulationSize',200);
    options=gaoptimset(options,'Display', 'iter');
    [x,fval,exitflag,output,population,scores] = ga(ObjectiveFunction,nvars,A,b,Aeq,beq,LB,UB,nonlcon,IntCon,options)

the problem in PopInitRange

many thanks

The error message is telling you that PopInitRange must have two rows, but the value you have given has 20 rows.
