In this code im reading sensor data in a loop for a specified ammount in a loop. I am trying to store the data in a table but can for the life of me figure out how to do that. here is what i have so far. Any help would be appriciated, or point me to domcumentation that will help. thank you in advance
while i < MaxDataLeng
i = i + 1;
temperature = readTemperature(bmp);
temp_f = ceil (temperature * (9/5)) +32;
pressure = readPressure(bmp);
Altitude = BalAltFunc (pressure, temp_f);
fprintf ('%d\n',i);
fprintf ('---------------------------------------------------------------------------------------------------\n');
fprintf ('temperature: %d F \n', temp_f);
fprintf ('pressure: %f0.1 hPa \n', pressure);
fprintf ('altitude: %d meters \n', Altitude);
fprintf ('---------------------------------------------------------------------------------------------------\n');
pause(Delay);
C = {'interval', 'temp', 'pressure', 'altitude'; i temp_f pressure Altitude;};
end
end

Initialize
T = table('Size', [0 4], 'VariableTypes', repmat({'double'},1,4), 'VariableNames', {'interval', 'temp', 'pressure', 'altitude'});
Then in your loop,
C = {i temp_f pressure Altitude};
T(end+1,:) = C;
You will probably want to remove the fprintf() from inside the loop.
