Hello Huang,
To achieve the functionality you described, you can follow these steps to filter records by a specific customer's name and then display the records in a sliding window format. Below is a sample code that demonstrates how to do this:
% Function to filter the table for records that match the specified customer's name.
function customerRecords = filterCustomerRecords(data, customerName)
customerRecords = data(strcmp(data.CustomerName, customerName), :);
end
% Function sorts the records by date and then displays them in a sliding window format.
% The window size and step size are adjustable.
function displaySlidingWindows(records, windowSize, stepSize)
records = sortrows(records, 'DateOfPurchase'); % Sort by date
numRecords = height(records);
for startIndex = 1:stepSize:(numRecords - windowSize + 1)
endIndex = startIndex + windowSize - 1;
disp(records(startIndex:endIndex, :)); % Display current window
end
end
% Example usage
customerName = 'John Doe';
windowSize = 10;
stepSize = 5;
% Filter and display records
customerRecords = filterCustomerRecords(data, customerName);
displaySlidingWindows(customerRecords, windowSize, stepSize);
Ensure that your table (data) has the correct column names and types as expected by the code. You can adjust the column names in the code to match those in your actual data.
