I am getting error in following line of code.

if(size(find(cfg.ch1==upper(str(j))),2)==0), valid=0; return; end;

and its called as: if(~checkValidGt(gt)), continue; end

Any solution please??

Whatever cfg is, it is not a structure or object

By the way you should consider isempty() instead of what you do with size().

You should consider

if ~any(cfg.ch1 == upper(str(j)))

cfg is a matlab script, where ch1 is defined.

You cannot reference variables in another script or function.

You can execute a script to have it change the variables in the current workspace, and then you can use that value.

You can can call a function that returns a value and use that value.

You can call a function that returns a structure and assign the structure to a variable and then refer to a field in the variable.

You can define a class that has the field as a property, using the syntax you are already using.

You can define a "package" cfg that has a function ch1 that you could call upon using the syntax you have now.

However there is no way to refer to the inside of a script.
