I'm not quite sure what is wrong with my code. I am trying to figure out a ranges from my y-axis to determine what to name certain peaks: For example, if the peaks lie within the range of 0.1-0.3, the are considered "twave", from 0.3-0.6 they are "rwave", and from 0.6 - 1 they are "wave".

Does anyone have any advice?

"equalize" is the file that I am reading

function [ pwave,rwave,twave ] = peakwaves( equalize )
peakwaves = findpeaks(equalize, 'MINPEAKHEIGHT',0.1);  %configures all of the peaks
a = length(peakwaves);
counter1 = 0;
counter2 = 0;
counter3 = 0;
for i = 0.1:a;
   if 0.3 < a && a < 0.6;
      counter = counter + 1;
      pwave(counter) = peaks(i);
  elseif .1 < a && a < 2.9;
      counter2 = counter2 + 1;
      twave(counter2) = peaks(i);
  else a < 1;
      counter3 = counter3 + 1;
      rwave(counter3) = peaks(i);
  end
end

When you wrote pwave(counter) = peaks(i); , peaks is not defined

Also a = length(peakwaves); is an integer, What [0.3, a] represent?

Try this

function [ pwave,rwave,twave ] = peakwaves( equalize )
peakwaves = findpeaks(equalize, 'MINPEAKHEIGHT',0.1);  
pwave = peakwaves(0.3 < peakwaves  & peakwaves < 0.6);
rwave = peakwaves(0.6 <= peakwaves  & peakwaves < 1);
twave = peakwaves(1 <= peakwaves &  peakwaves < 2.9);
