any help me with this error ,((Attempted to access HydrogenProduced(1); index out of bounds because numel(HydrogenProduced)=0. Error in main (line 17) CurrentHydrogenInTank(1) = IniHydrogen + HydrogenProduced(1) - H2_consumption(1); ?

clear all;
%Csur = load('Csur.csv');
H2_consumption = load('H2_consumption.csv');
Psur = load('Psur.csv');
%%%C_grid = 0.17
IniHydrogen = 9000;
H2_consumption = 0.11*H2_consumption;
H2_consumption =modifyConsumption (IniHydrogen, H2_consumption, Psur);
%H2_consumption = modifyConsumption (IniHydrogen, H2_consumption, Psur);
%H2_consumption = H2_consumption*0.7;
HydrogenProduced = calculateMinCost(H2_consumption,IniHydrogen,Psur');
%plot(x_opt);
CurrentHydrogenInTank = zeros(size(HydrogenProduced,1),1);
(((((CurrentHydrogenInTank(1) = IniHydrogen + HydrogenProduced(1) - H2_consumption(1))))); line 17 
for i = 2:size(HydrogenProduced,1)
    CurrentHydrogenInTank(i) = CurrentHydrogenInTank(i-1) +  HydrogenProduced(i) - H2_consumption(i);
end
%hour = 1:1:24;

figure;

Abdulla - the error message is telling you that HydrogenProduced is an empty matrix (the number of elements, numel, are zero). You may want to step through your code and see why calculateMinCost is returning this empty matrix.
