how can i extract feature's of gyroscope,accelerometer and magnetomere?

I am a new learner about sensors. I have no knowledge about this sensors. However I have done some sensor module which contains with accelerometer,gyroscope and magnetometer. All of them have 3 axis data (X,Y,Z).Now i have data as a TXT file format but I couldn't f开发者_运维百科ind any solution for extraction this data features. I am going to use this data with NNet. Could anyone help me with making program in Matlab,please? Any suggestion and opinion will be useful for me. Thanks in advance!

As zellus suggested, the reading from textfile is well documented in MATLAB. Look for functions textread or csvread.

As I understand it, you are looking for help understanding the data that you have collected. You may get some answers here, but you are most likely better off asking what you should be looking for in a physics/engineering related forum, then coming back here for help implementing your code if need be.

As a starting point, you could try:

• Plotting the change in the data over time, for each direction.
• Looking at the magnitude of each of accelerometer, gyroscope and magnetometer data (using norm), and plotting these over time
• Making a scatter plot of the norms of, for example, acceleration vs magnetometer - is there any correlation?
• Likewise a scatter plot of X acceleration vs Y acceleration, or X vs Z etc.

Remember, in MATLAB, the plotting tools are your friend.
