clear all issue in eidors and matlab

Eidors is an open source simulation tool for Electrical Impedance Tomography (EIT). I intend to share some of my learnings with the use of this softaware.

On way to use it, is to use .m file (matlab script file) to run the desired simulation. Prior running any script EIDORS requires to run its startup.m script to setup is variables.

Personnaly I start all my scripts with the commands:

close all; %closes all open graphs
clear all; %clears all workspace variable

Doing so arises an error message from EIDORS:

??? Error using ==> eidors_obj>test_install at 87
EIDORS not correctly started. Did you do ">>run /path/to/eidors/startup"
Error in ==> eidors_obj at 69
      test_install
Error in ==> ng_mk_cyl_models at 89
fmdl = eidors_obj('get-cache', cache_obj, 'ng_mk_cyl_models' ); 

The reason is that the "clear all:" command do also clears EIDORS variables. The solution is to replace

clear all; 

by

clear;
