Get I and Q

function y = getiq('data', 'rate at which calculated per second, 'center frequency')

function y = getiq(x,freq)
this takes in the frequencies X that were received at a rate of FREQ and gives you a complex value which is I and Q - this is used when you have frequency X changing and the phase is cumulative - meaning it does not start each new frequency at the same spot

OR

function y = getiq(data,freq,fc)
this takes in frequencies X that were received at a rate of FREQ and gives you a complex value which is I and Q based around a center frequency FC this is used when you have frequency X changing and the phase is cumulative - meaning it does not start each new frequency at the same spot
