WebNov 14, 2012 · I want to calculate Pearson's correlation coefficent in Matlab (without using Matlab's corr function). Simply, I have two vectors A and B (each of them is 1x100) and I am trying to calculate the Pearson's coefficient like this: P = cov (x, y)/std (x, 1)std (y,1) I am using Matlab's cov and std functions. WebApr 29, 2014 · The Matlab-function corrcoef gives me a complex correlation coefficient (cc). Interpreting it as usual suggests, that the abs of the cc means the characteristics of correlation. The phase must be the phase shift between the signals. Unfortunately, I've nowhere found a documentation about complex correlation coefficients.
