function [peaks, peakno]= Accelerometerdata(Acceleration)
z = Acceleration.Z;
smtlb = sgolayfilt(z,9,21);
peaks=findpeaks(smtlb,t,'MinPeakDistance',1);
peakno=numel(findpeaks(smtlb));
end

Is there a particular reason your last line is not
peakno = numel(peaks);
??
I would suggest that you pre-allocate peaks and that you pass the maximum size as NPeaks to findpeaks() . That will prevent Simulink from complaining about peaks being unknown size.

Suppose that you did manage to return a variable-length list of peak heights. What would you do with the variable-length list downstream ?
