[Scilab-users] check if variable within structure is available

[Philipp Mühlmann]

Is there a way to check if a variable within a structure is available?


Example:

There is a structure   handle  containing different variables.


e.g:

handles.status     // contain Status info of different pushbuttons --> in
fact status is a structure itself:  handles.Status.pb1; handles.Status.pb2;
handles.I_ORG   // contains original Image --> array
handles.I_RES    // contains resulting Image  --> array


Now I want to check if  handles.I_RES existst



exists('handles.I_RES' , 'a')    will return "0" even if handles.I_RES does
exist
isdef  ('handles.I_RES' , 'a')    will return "F" even if handles.I_RES
does exist


Thank you,
Philipp
