[Scilab-users] Variables visibility in functions

[Stéphane Mottelet]

Here is a small example. Although the name of fields of returned struct 
is very cryptic, the information you need can be easily recovered.


mputl(["function [y] = foo(x)"
"y = x + a"
"y = y + b"
"endfunction"],"slint_test.sci")
out  =  slint("slint_test.sci",%f)
if  isfield(out.info,"00003.Uninitialized")
     s  =  out.info("00003.Uninitialized");
     for  i=1:length(s)
         disp(s(i).msg)
     end
end
