Question

I would like to get the error rate of 2 vectors?

like

                # incorrect numbers           6
error rate  = ______________________    =    ____ 
               # total numbers(size)          15

here are 15 numbers, 9 are correct
x is the true answer (the reference), and y is vector with answers
I would like to compare them and get error rate:

x= [1 ,1,1, 1,1, 1,1,1,1,1, 1,-1,-1,-1,-1] 
y= [-1,1,1,-1,1,-1,1,1,1,1,-1, 1,-1, 1,-1]   

• Also is it corret what I am doing?
  Ok I was wrong about the formula I updated it.

Answer 1

If you want the error rate, then you want the number of incorrect values divided by the total number of values. You can do this using the relational operator ~= and the function MEAN:

errorRate = mean(x ~= y);
