How to use structure variables from one matlab file inside a classdef which creates function and use in another matlab file

Hi,

I am new to OOP in matlab.

I have lot of data which I classify into different m files. and creating functions inside a classdef which can be used directly in one outfile m file.

I have attached duplicate scripts for reference.

I am unable to run the final m file. Its throwing error as

Unable to resolve the name par.a.

Error in funcs.func1 (line 7)

res = (x*(par.a +par.b +par.c))+con.gravity;

Error in Outfile (line 5)

result = funcs.func1(z);
