What zeros?

Did you raise any question regarding use of zeros of df? What was your question and what you are expecting?

I know zero is represented by 0. How and why you want to use here?

Jeez you want to use initilization?
If you are using a loop and filling values into it, you have to initalize the array using zeros.
If you are not using loop and getting the LHS by vectorization, no loop is needed.

It seems there is a problem in Snc solution. ds and dc are vectors of 1601 elements whereas df has 300 elements.
Snc= ((nc/Nm).*((nf.^2-Nm.^2)./(nf.^2-nc.^2)).*(dc./(ds+df+dc)).*(2.*(Nm.^2./nc.^2)-1));
The same in Sna line:
Sna= ((na./Nm).*((nf.^2-Nm.^2)./(nf.^2-na.^2)).*(da./(ds+df+da)).*(2.*(Nm.^2./na.^2)-1));
I don't know the aim of df but try initializing the same length as ds.
