Random allocation of variables

Question

0 个投票

Hi

I have two Signals, say Sig1 and Sig2 - both sine waves with different amplitudes. Now I have two other variables, RHand and LHand, standing for the right respectively left hand. What I want to do is to randomly allocate the signals at the start of an experiment to one of the two hands - how is that done fastest?

I can think of something like:

    randper = randperm(2);
    Sig = [Sig1,Sig2];
    LHand = [];
    LHand = Sig(randper(1));
    RHand = Sig(randper(2));

..but that seems somehow overly complicated..?

randper will be 1X2, then your LHand and RHand will be 1x1 each. Is that you want?

I want to randomly allocate at the start of my code Sig1 and Sig2 either to the left or to the right hand..not sure what you mean

if rand < 0.5
  LHand = Sig1;
  RHand = Sig2;
else
  LHand = Sig2;
  RHand = Sig1;
end
