this is not the correct way to use arrayfun.
have you tried reading the help before using it?

Try 

help arrayfun 

This will tell you that

"The first input argument FUNC can be a string, a function handle,
 an inline function, or an anonymous function. "        

If you are not confortable using arrayfun, just do

for ii = 1:numel (xx) 
 dd(ii) = getz(xx(ii));
endfor

As for the error:

This is expected because you are invoking 'getz' with no input arguments
and getz has a check to avoid this.


> z=-(vloss/(sqrt(2*pi)*k* getz(dd))).* exp(-yy.^2/(2* (k*getz(dd)).^2));

This line looks very confusing to me ...
why would you use 'getz(dd)' in this line if you have already evaluated

dd(ii) = getz (xx(ii))

HTH,
