hi,
I have 2 vectors A and B
A=[0.0252653330054456 0.0252653330054481 0.0252653330347238 0.0252656701005406]
B=[1.83588753363655 1.83588753363655 1.83588753363753 1.83588754495825]
I want to get a similarity value between 0 and 1, using a correlation coefficient. Is their any function in Matlab to get it?
cheers

Typing
docsearch correlation
turns up the corrcoef() function as the first hit.
doc corrcoef
for details on this function, to see if it does what you need.

no, the pearson corr eoeff gives between -1 and 1, not 0 and 1. And of course, I looked at the doc.
