How to determine the uncertainty between sensors data using matlab ?

Dear all.

I have the following problem, I have 6 sensors, one of them is fixed and the (5) others are with different positions.

my interest is to calculate the uncertainties in the sensors data vectors.

I tried to use dtw instruction to calculate the distance between them, but could not have a clear understanding on how to interpret the values obtained.

can any one suggest a solution to this problem? using matlab functions.

I would highly apreciate your help
