Hi I have the following code which I am trying to loop. the loop isn't working however and I don't know why
PVsupply = [0 0 0 0 0 0.05 0.1 0.11 0.13 0.13 0.15 0.15 0.15 0.15 0.145 0.145 0.14 0.135 0.08 0.05 0 0 0 0];
hourly_daily_PV = PVsupply(:);
hourly_annual_PV = repmat(hourly_daily_PV,365,1);
WTsupply = [10 10 10 10 25 25 25 15 15 15 15 15 15 15 35 35 35 35 35 10 10 10 10 10 ];
hourly_daily_WT = WTsupply(:);
hourly_annual_WT = repmat(hourly_daily_WT,365,1);
number_panels = 1:10:100;
number_turbines = 1:1:5;
for idx_number_panels = 1:length(number_panels) % range of PV panel units examined
for idx_number_turbines = 1:length(number_turbines) % range of wind turbine units examined
for number_batteries = 1:5 % range of battery units examined
for h=2:25 %# hours
hourly_total_RES(idx_number_panels,idx_number_turbines,number_batteries, h) = hourly_annual_PV(h)*number_panels(idx_number_panels) + hourly_annual_WT(h)*number_turbines(idx_number_turbines);
end
end
end
end

what is your error message

The error I am getting is that the "hourly_total_RES" variable only calculates up to h = 5, whereas it should be going to h = 25 as shown above. The size(hourly_total_RES) is 1 1 1 5, wheras it should be size(hourly_total_RES) = 10 5 5 24

I don't get any error, nor the size is [1 1 1 5] with the data and script you supplied.

i am not getting any errors; before running your code use
clear
if it does'nt work check if any of your variables are not shadowed by any function or file with the same name in your working folder
