Variable declaration in startup.m not working in MATLAB -

i'm trying declare magic number constants need access in every script. made file load_constants.m in my_path looks like:

magic_number = 10; other_magic_number = 12;

my startup.m looks this:

% add bunch of packages addpath ~/documents/matlab/some-package  userpath(my_path) load_constants

but when try access magic_number in command window:

undefined function or variable 'magic_number'.

directly declaring variables in startup.m doesn't work either. how fix this?

this normal behavior, startup.m function , variables declare inside function local function (and vanish when going out of scope):

function [] = startup() %[     magic_number = 10; %% local variable %]

use assignin function have magic_number visible base workspace:

function [] = startup() %[     assignin('base', 'magic_number', 10); % value visible 'base' workspace %]

note having magic_number value visible not scripts functions also, may better create magic_number.m function , add path:

function [v] = magic_number() %[     v = 10; %]

which can called without brackets (i.e. syntax variables)
