hi guys i want to calculate the difference between vector element as [0 1 1 0 1 1 0] which should give 0-1=1,1-1=0,1-0=1,0-1=1,1-1=0,1-0=1,,, and the sum answer should be 4. how to do this. and what if there's 12 vector within one matrix.

It looks like you want the sum of the absolute value of the differential of those numbers? You get your first answer like this:

abs_diff = abs(diff([0 1 1 0 1 1 0]))

You would then sum these values. If all you want is the final answer, this is how to do it:

answer = sum(abs(diff([0 1 1 0 1 1 0])))

In order to answer this you would need to explain what you are looking for: one number per row, one per column, a giant sum (and if so in what dimension)?
