Find Average Peaks Function

I'm trying to find the average peaks from a code script I made. I currently am using the "findpeaks" function with a minimum y-axis value necessary. Example is

[pksR1,LcsR1]=findpeaks(filt_RLE,"MinPeakHeight",55);

What function can I call to get the mean bewteen the peaks within the code.

"What function can I call to get the mean bewteen the peaks within the code."

You want to find the mean of all the peaks you obtained?

The mean value of the function between any two peaks would be —

x = linspace(0, 10, 250).';
filt_RLE = 50 * sin(2*pi*x*1.5) .* cos(2*pi*x/10) + 30;

[pksR1,LcsR1]=findpeaks(filt_RLE,"MinPeakHeight",55);
LcsR1 = LcsR1.';

for k = 1:numel(LcsR1)-1
    meanv(k,:) = mean(filt_RLE(LcsR1(k) : LcsR1(k+1)));
end

figure
plot(x, filt_RLE)
hold on
plot(x(LcsR1), filt_RLE(LcsR1), 'r^')
hold off
yline(55, '--k')

Results = table(x(LcsR1(1:end-1)), x(LcsR1(2:end)),meanv, 'VariableNames',{'Peak Start','PeakEnd','Mean'})

Results = 9×3 table
    Peak Start    PeakEnd     Mean
