undefine variable.

[astie darmayantie]

Here i have 2 .m file which are connected. because the first .m file will call for another function in the second .m file. 
So here's the mechanism i call a function in the first .m and the first .m will call another function listed in the second .m file to complete the calculation.
The problem is the second .m file can not read the variabel i have defined in the first .m :(
and keep having these error

% here i call a function from the first .m file
[edgelist, labelededgeim]=edgelink(edgeim,10);

warning: nested functions are coerced into subfunctions in file /usr/share/octave/3.6.2/m/image/cleanedgelist.m
error: `edgelist' undefined near line 310 column 17

i already attach the .m file. i got confused because these code works very well on matlab.

Thankyou
