Warning: Warning: feval on script names will not work, or may work differently,
in a future version of MATLAB. To make your code insensitive to any change
and to suppress this warning message:
- Either change the script to a function.
- Or use eval instead of feval.
The script file in question is myfun.

Error using feval
Attempt to execute SCRIPT myfun as a function:
C:\Matlab_codes\myfun.m
Error in fsolve (line 241)
fuser = feval(funfcn{3},x,varargin{:});
Error in positioning_by_ranging (line 11)
[solution,fval] = fsolve(@myfun,[x0,y0,z0],options) % Call solver
Caused by:
Failure in initial user-supplied objective function evaluation. FSOLVE cannot continue.

What is in myfun.m ? You show us fun being constructed and it would normally be assumed you were going to fsolve fun but you fsolve the unknown myfun instead.
