Code:
Y = readtable('lab1_section1_9hz000.xlsx','Range','E1:AJ180');
Y1 = table2array(Y);
Y2 = detrend(Y1);
for i=1:32
[pks,locs] = findpeaks(Y2(:,i));
meanWH(i) = mean(pks);
meanWL(i) = mean(diff(locs));
end
Error
>> Lab1_Wave_Sensor
'findpeaks' requires Signal Processing Toolbox.
Error in Lab1_Wave_Sensor (line 8)
[pks,locs] = findpeaks(Y2(:,i));

it believes that Signal Processing Toolbox is either not installed or not licensed.
