Kalman filter accelerometer, gyroscope and magnetometer

Hi, I have a question. I have to design a Kalman filter for accelerometer, gyroscope and magnetometer and apply the sensor fusion to it. The sensor data is in three different .txt files. How can I change the filter in the link to pass my files to it? Thanks in advance!

Hi,

From my understanding, you are trying to extract data from the .txt files and use the data to design Kalman filter

You can use the following code and obtain required data from your files

fileID = fopen('data.txt');
Out = textscan(fileID,'%f %f %f');
A = Out{1};
B = [ Out{2} , Out{3} ];

For more information, you can refer to textscan
