I have an 9 axis sensor and I have the data in matlab. I am wanting to calculate the resultant vector of acceleration, the resultant angular velocity for gyroscope.. and magnetometer.

In excel i would simply SQRT(accx^2+accy^2+accz^2) . this would be the resultant.

My question is how do i calculate this? Then, how do I automatically calculate this for every data point?

Thankyou!!

Hi I am just wondering which MPU you are using for reading the data because i am having difficulties to read data out of the MPU 9250?

Thank you

在 MATLAB Online 中打开

% some random data for demo 
accx = rand(10,1) ;   
accy = rand(10,1) ;   
accz = rand(10,1) ;   
R = sqrt(accx.^2+accy.^2+accz.^2) ;

"Is there a way to automatically calculate this for every row?"

That is what KSSV's answer does: it returns a 10x1 vector, each row corresponds to the same rows of the input 10x1 vectors.

Forget about how Excel works: neither MATLAB nor any other language works like a spreadsheet.

ok thankyou, that makes sense. It worked perfectly!
