Cross correlation of a vector is very easy. You simply create a FIR filter (or the FFT-based FIR filter, doesn't matter), set one vector as the taps and pass the other vector through it. This technique is used when one vector is static and the other is a streaming input signal. If both vectors are signal streams, you could multiply both streams together and put them through a FIR filter that is full of 1's and is the length of the vectors you want to correlate. I feel like there's a better way here, but I'm not thinking of anything right now. For matrices, you might have to think harder about how to use this.
