pls help me fix this i trying to find the earning and savings of it trough loops but it say the index exceed numbers of array

savings=[];%initial saving vectors

earnings=zeros(1,1212);%initial earning vectors

T_earnings_Jul=0;%initial total earning vectors up to jul

earnings_Aug=zeros(1,293);%initial earning vectors up to Aug

T_earnings_Aug=0;%initial total earning vectors up to Aug

total_earning=0;

% Loop through each day to calculate savings and earnings

for i = 1:1505 % total of 1505 day

savings(i) = O_Consumption(i).*Cost(i);

end

%from April 06 2020

for i =1:1212

earnings(i)=e_out(i).*Feed(i);

T_earnings_Jul=T_earnings_Jul+earnings(i);

end

%from auguest 1 2023

for i= 1213:1515

%less than 10kwh

if e_out(i)<=10000

earnings(i)=e_out(i).*Feed(i);

T_earnings_Aug=T_earnings_Aug+earnings(i);

end

%more than 10kwh

if e_out(i)>10000

earnings_Aug(i)=((e_out(i)-10)./100)+0.88;

T_earnings_Aug=T_earnings_Aug+earnings_Aug(i);

end

end

total_earning=T_earnings_Jul+T_earnings_Aug;

fprintf('\n\nthe total savings earned is $%.2f\n',sum(savings));

fprintf('\n\nthe total earnings earned is $%.2f\n',sum(total_earning));

code is above

Index exceeds the number of array elements. Index must not exceed 1505.

Error in Q2 (line 52)

if e_out(i)<=10000

error is above

Hi Elisa

The error you are encountering is due to the loop index exceeding the number of elements in the array. The loop is iterating from 1213 to 1515, but your array "e_out" only has 1505 elements.

You can change the loop as follows:

for i = 1213:1505

To avoid indexing errors, you can use MATLAB's built-in "length" function to determine the size of your arrays dynamically.

Hope this helps!
