How can I change this code to make a header for each column like for instance accel X, accel Y, accel Z?

function [] = i2c_sensor()

a = arduino('COM3', 'UNO');

imu = mpu6050(a,'SampleRate',50,'SamplesPerRead',10,'ReadMode','Latest');

for i=1:10

accelReadings(i,:) = readAcceleration(imu);

display(accelReadings(i,:));

pause(1);

end

end

Hi @WAN NOR NAZIRA MUSTAPA KAMAL,

The appropriate data type you are looking for is the table in MATLAB. This data structure allows you to assign headers to each column. Below is an example, as referenced from the official documentation:

LastName = {'Sanchez';'Johnson';'Li';'Diaz';'Brown'};
Age = [38;43;38;40;49];
Smoker = logical([1;0;1;0;1]);
Height = [71;69;64;67;64];
Weight = [176;163;131;133;119];
BloodPressure = [124 93; 109 77; 125 83; 117 75; 122 80];

T = table(LastName,Age,Smoker,Height,Weight,BloodPressure)

T = 5×6 table
     LastName      Age    Smoker    Height    Weight    BloodPressure
    ___________    ___    ______    ______    ______    _____________

    {'Sanchez'}    38     true        71       176       124     93  
    {'Johnson'}    43     false       69       163       109     77  
    {'Li'     }    38     true        64       131       125     83  
    {'Diaz'   }    40     false       67       133       117     75  
    {'Brown'  }    49     true        64       119       122     80

Hope this helps add header column !
