I am looking for a code for matlab analysis of my data, I want to calculate water bill for every 100 litre=1USD, for 1 month. So that the user can get total water consumption bill at the end of the month. Please help.

Thanks it worked, but i didn't got the requided notification message. I needed the data of total water used and bill amount. Here is the code, please check if i did something wrong.
% Enter your MATLAB Code below
% Read Output Water Quantity over the past month from a ThingSpeak channel and write
% the average to another ThingSpeak channel.
% Channel 1035265 contains data from the MathWorks water supply station, located
% in Natick, Massachusetts. The data is collected once every day. Field
% 3 contains output liquid quantity data.
% Channel ID to read data from
% Output Liquid Quantity Field ID
outputliquidqantityFieldID = 3;
% If your channel is private, then enter the read API Key between the '' below:
% Get Output Liquid Quantity data for the last 30 days from the MathWorks water supply
% the Documentation tab on the right side pane of this page.
% Calculate the Cost
display(Billing_cost,'Total Billing Cost (INR)');
Water = sum(data(:, 2));
apiKey = 'TAK1S83KIQN0BBLNS';
alertSubject = sprintf(" Water consumption exceeded 100 kl!");
if Water >= 100
end

This sounds like a very interesting project. I wonder what sensor you are using to track the water consumption.
It sounds like you need help with the sprintf function. This line seems to be missing a format specifier.
Have a look at the documentation for sprintf.
