Date=datetime(raw.textdata(2:end,1),'InputFormat','dd-MMM-yy');%convert the data to date time
yr = year(Date); % Extract the year
mnth = month(Date); % Extract the month
% Create an array for the year-month combinations
yr_Month = yr * 100 + mnth;%example 202004
% Get unique year-month combinations
u_Months = unique(yr_Month);
%create month label in 'MMM yy" format
m_Labels = strings(length(u_Months), 1);
% Initialize vectors for monthly sums
m_sum_Production = zeros(length(u_Months), 1);
m_sum_T_Consumption = zeros(length(u_Months), 1);
m_sum_O_Consumption = zeros(length(u_Months), 1);
% Calculate the sum for each unique month-year combination
for i = 1:length(u_Months)
cur_Month = yr_Month == u_Months(i); % Logical index for the current month-year combination
m_sum_Production(i) = sum(Production(cur_Month)); % Monthly sum of Production
m_sum_T_Consumption(i) = sum(T_Consumption(cur_Month)); % Monthly sum of Total Consumption
m_sum_O_Consumption(i) = sum(O_Consumption(cur_Month)); % Monthly sum of Own Consumption
% Generate the corresponding 'MMM yy' label
yr_Part = floor(u_Months(i) / 100); % Extract the year
m_Part = mod(u_Months(i), 100); % Extract the month
% Create a datetime object for the first day of the month
m_Date = datetime(yr_Part, m_Part, 1);
% Format month as 'MMM yy'
m_Labels(i) = datetime(m_Date, 'mmm yy'); % Create the 'MMM yy' label
end
code is above
Unable to use a value of type datetime as an index.
Error in Q3 (line 15)
mnth = month(Date); % Extract the month
