Hello everyone.
I am trying to use both xcorr(var1,var2,0,'coeff' and corrcoef in order to get a correlation coefficient of two vectors (I want to see how "similar" they are).

The thing is, sometimes I need to insert a vector of zeros into that calculation and the I get NaN as a result.

It is very important for me to be able to correlate between a vector of zeros and a vector of really small numbers ( both of same length, of course), and get a relatively good correlation between the two (relative to a vector of ones with a vector of small numbers, for example).
