Help me, i'm new to MatLab and I got this error after typing this code. Can somebody help me please and find a solution. Thanks.

    function expected_freq = feature8(data,fs)
    cutoff = 100;
    data=data/max(abs(data)); 
    b= fir1(100,2*cutoff/fs,'high',chebwin(101)); 
    data=conv(data,b); 
    t=60e-3;
    wl=2^nextpow2(t/(1/fs));
    w=hann(wl,'periodic');
    [F,T,P]=spectrogram(data,w,[],wl,fs);
    a=sum(P,1);
    temp1 = repmat(a,[],length(F));
    PMF=P./temp1;
    temp2 = repmat(F,1,length(T)); 
    freq = sum(PMF.*temp2);
    expected_freq= std(freq);
    end
