I am looking at an FFT graph and trying to output the max amplitude values between the frequency range of 0.09:0.11,0.19:0.21, and 0.24:0.26. I have a two column matrix. The first column is amplitude values and the second column is frequency values.

idx=(FFTDataCKASRoll(:,2)>=.09&FFTDataCKASRoll(:,2)<=.11)|...
(FFTDataCKASRoll(:,2)>=.19&FFTDataCKASRoll(:,2)<=.21)|...
(FFTDataCKASRoll(:,2)>=.24&FFTDataCKASRoll(:,2)<=.26);
m=max(FFTDataCKASRoll(idx,1));

max(yourMat( yourMat(:,2)>0.09 && yourMat(:,2)<0.11 ,1))
for the first range and so on?
