Start and end time for off-peak hour is from 00.00 to 07.00 and 21.00 to 24.00. The power usage price at this time interval is 03.00 cents. Start and end time for mid-peak hour is from 11.00 to 17.00. The power usage price at this time interval is 05.00 cents. Start and end time for peak hour is from 07.00 to 11.00 and 17.00 to 21.00. The power usage price at this time interval is 07.00 cents.
I want to code that intervals . Please help me how to do it.

I guess that making a table that stores these times will help. I have attached a code below, please tell if it helps-
tariff = table('Size', [0 4], 'VariableTypes', {'duration', 'duration', 'string', 'double'});
tariff.Properties.VariableNames = {'Start_Time', 'End_Time', 'Tariff_Name', 'Cost'};
tariff = [tariff; {duration('00:00', 'InputFormat', 'hh:mm'), duration('07:00', 'InputFormat', 'hh:mm'), 'Off-peak', 3.0}];
tariff = [tariff; {duration('07:00', 'InputFormat', 'hh:mm'), duration('11:00', 'InputFormat', 'hh:mm'), 'Peak', 7.0}];
tariff = [tariff; {duration('11:00', 'InputFormat', 'hh:mm'), duration('17:00', 'InputFormat', 'hh:mm'), 'Mid-peak', 5.0}];
tariff = [tariff; {duration('17:00', 'InputFormat', 'hh:mm'), duration('21:00', 'InputFormat', 'hh:mm'), 'Peak', 7.0}];
tariff = [tariff; {duration('21:00', 'InputFormat', 'hh:mm'), duration('00:00', 'InputFormat', 'hh:mm'), 'Off-peak', 3.0}];
This code stores your intervals in the form of a table, as shown below-

Follow Pullak's example to create the table first. (NB: depending on the release you're using, you may have to revise his syntax--w/ R2017b here I had to do a fair amount of retrofitting as various features he used weren't yet implemented --starting with duration() not yet accepting a string date as input.
