Error using Zeros, size input must be integers.

Hi

I get this message (error using zeros, size input bust be integers ) when running this code. anyone knows how to fix this ?

Qd=zeros(size(Q,1)/24,length(A));
for i=1:length(A)
  for d=1:size(Q,1)/24
    bk=Q(1+24*(d-1):24*d,i);

    k=~isnan(bk);
    Qd(d,i)=sum(bk(k))/length(k);
  end
end

thanks

Qd=zeros(round(size(Q,1)/24),length(A));
for i=1:length(A)
  for d=1:round(size(Q,1)/24)
    bk=Q(1+24*(d-1):24*d,i);

    k=~isnan(bk);
    Qd(d,i)=sum(bk(k))/length(k);
  end
end

The indices of matrices in MATLAB should be poittive integers.. when you are using size(Q,1)/24, if size(Q,1) is not multiple of 24 you will get a fraction and it will throuw error. So using round will round the number into nearest integer.
