I have the following code:

for k = 1:N

W(i,k)=W1*(cB(i,k))^W2;

Fluor(i,k)= cB(i,k)*W(i,k)*dx;

end

FL = sum(Fluor(i,1:N),'all');

Sometimes cB(i,k) is equal to zero and because W2 is a negative number this, I guess, ultimately results in Fluor (i,k) equal to NaN. Is there a way to have Matlab insert zero instead of NaN for Fluor(i,k). Ultimately, I'm interested in FL, so an alternative might be to have Matlab skip any values of NaN when summing the row in table Fluor.
