Simulink real time vector accumulation

I am currently running simulink real time in which a packet input from a CAN Bus that takes the signal of a microphone. I wish to take this data and analyze the frequency and amplitude of the signal. However, the CAN Bus inputs data one element at a time at 1000Hz, in order to make these calculations I require a vector of data points. Is there a way to create a vector of signal points in simulink?

Thanks for your help.

hi

you should use a buffer (specify the lentgh)
