Calculate Signal Magnitude Area of an accelerometer in Matlab

Hi to all,

I have accelerometation data in x,y,z format and I want to compute the normalized signal magnitude area (SMA) of my signal according to this:

Assuming that I choose a time interval of 0.1 sec , how would I do this in matlab? Thanks in advance

I would use the trapz function to do the integrations.

Write your code to calculate MSA, and if you have problems, post or attach your code, a sample of your signal data, and a full description of any problems you have, with complete error messages if your code generates them.
