I am unable to solve this array dimensional error can someone help please?

n error occurred while running the simulation and the simulation was terminated

Caused by:

Index exceeds array dimensions. Index value 2 exceeds valid range [1-1] for array 'P_battery'. Code generation does not support growing arrays via indexing except by using end+1.

Error in 'vanadiummicrogrid/MATLAB Function' (line 13)

P_battery(i) = P_battery;

Here is my code

function P_battery = EMS(netP, soc)
soc_max = 95; % percent
battery_max = .116; %kW

for i=1:length(netP)
    if netP(i) > 0 && soc < soc_max
        P_battery = min(netP(i), battery_max);
    else
        P_battery = max(netP(i), battery_max);
    end
    P_battery(i) = P_battery;
end

Also can someone tell me whether this program is structured well? I just need it so if the power exceeds the need of the load then the power reroutes to the battery. Thank you!

[Walter Roberson]

function P_battery = EMS(netP, soc)
soc_max = 95; % percent
battery_max = .116; %kW

P_battery = zeros(1, length(netP));

for i=1:length(netP)
    if netP(i) > 0 && soc < soc_max
        P_bat = min(netP(i), battery_max);
    else
        P_bat = max(netP(i), battery_max);
    end
    P_battery(i) = P_bat;
end
