I believe you want the 'continue' statement. See `help -i continue` at
your Octave prompt.

You could also negate your if and enclose all of the loop's innards in
that if block.

Something like:

for i = 1:10
  if (f(a,i)~=0.0)
    ...
    ...
    ...
  endif
endfor

(Sorry, I don't know the corresponding Fortran syntax.)
