How to use logic operation with lookup table

I have a lookup table generating a 24-hour time-series profile. I want to compare the values from the profile with a constant and generate another time-series signal based on that. how do i do it?

Hey @Shreya Dutta, To compare values from a 24-hour time-series profile with a constant and generate a new time-series signal based on that comparison, you can follow these steps in MATLAB:

1. Initialize Your Time-Series Data: Load or define your 24-hour time-series profile.
2. Define the Constant: Set the constant value you want to compare against.
3. Perform the Comparison: Compare each value in the time-series profile with the constant.
4. Generate the New Signal: Create a new signal based on the result of the comparison.

Here's an example MATLAB script to illustrate this process:

% Example: Generate a 24-hour time-series profile
% Let's assume the profile is hourly data for a day (24 values)
timeSeriesProfile = rand(1, 24) * 100;  % Example data: random values between 0 and 100

% Define the constant to compare against
constantValue = 50;

% Initialize the new time-series signal
newTimeSeriesSignal = zeros(1, 24);

% Compare each value in 
the time-series profile with the constant
for i = 1:length(timeSeriesProfile)
    if timeSeriesProfile(i) > constantValue
        % Example condition: Set new signal to 1 if profile value is greater than the constant
        newTimeSeriesSignal(i) = 1;
    else
        % Otherwise, set it to 0
        newTimeSeriesSignal(i) = 0;
    end
end

% Display the original and new time-series signals
disp('Original Time-Series Profile:');
disp(timeSeriesProfile);

disp('New Time-Series Signal:');
disp(newTimeSeriesSignal);

Explanation

• Time-Series Profile: In this example, a random time-series profile is generated with values between 0 and 100. You should replace this with your actual data.
• Constant Value: The constant value for comparison is set to 50. Adjust this to your desired threshold.
• Comparison Logic: The script compares each value in the timeSeriesProfile with the constantValue. If a value is greater than the constant, the corresponding position in newTimeSeriesSignal is set to 1; otherwise, it is set to 0.
• Output: The script displays both the original and new time-series signals.
