How do you cross-correlation in Matlab?
r = xcorr( x , y ) returns the cross-correlation of two discrete-time sequences. Cross-correlation measures the similarity between a vector x and shifted (lagged) copies of a vector y as a function of the lag.
How to calculate cross-correlation?
Cross-Correlation
It is calculated simply by multiplying and summing two-time series together. In the following example, graphs A and B are cross-correlated but graph C is not correlated to either.
How does Corr work in Matlab?
rho = corr( X ) returns a matrix of the pairwise linear correlation coefficient between each pair of columns in the input matrix X . rho = corr( X , Y ) returns a matrix of the pairwise correlation coefficient between each pair of columns in the input matrices X and Y .
How do you find the correlation between two variables in Matlab?
R = corrcoef( A ) returns the matrix of correlation coefficients for A , where the columns of A represent random variables and the rows represent observations. R = corrcoef( A , B ) returns coefficients between two random variables A and B .
