I have an array of 14,400 complex expressions (X + iY) and I wanted to do a complex autocorrelation on the array. I know there's an autocorrelation VI in LabVIEW, but does it support complex numbers? I have a feeling it doesn't. If not, how would I go about doing this? Thanks.
Hi, You can calculate autocorrelation of complex array in such a way: C=X+i*Y - your array B(C)= - corellation which you want to calculate.
So B(C)=B(X+i*Y)=
And as a result we have that autocorrelation of (X+i*Y) is equal to the sum of 1. Autocorrelation of X 2. -(Autocorrelation of Y) 3. i*(Crosscorelation of X and Y) 4. i*(Crosscorelation of Y and X)
