Matlab Cross correlation vs Correlation Coefficient question

Question

I\'m writing a program in C++ but using data from matlab involving Cross Correlation. I understand that when I do a correlation on 2 sets of data it gives me a single correl

Answer 1

To be clear about several concepts.

1. Cross-correlation vs. cross-covariance. The main difference is that cross-covariance normalize the data by subtracting the mean.

2. cross-covariance vs. normalized cross-covariance. The later one is divided by the standard deviation of the the input.

3. normalized cross-covariance and correlation coefficient. The later one is the special case of the former one at delay=0.
