Read MMA8542 accelerometer i2c in Matlab using Raspberry pi

Hello!

I need help please, I try to read the position [x,y,z ] in matlab, here is my code,

mypi = raspi;

scanI2CBus(mypi,'i2c-1');

myi2c = i2cdev(mypi,'i2c-1','0x1D');

output-1 = read(myi2c, 8)

In my code I have this result

0 13 248 84 252 254 64 0

My problem here is all value will be the same even if I change the location of the sensor. How I can get the position [x,y,z] , my sensor is MMA8542q

Thank you!
