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)

amazon web services - S3 Pre-signed POST validate file type? -

i know it's possible put limit on file size content-length-range header. possible validate file type? https://docs.aws.amazon.com/amazons3/latest/dev/httppostforms.html#policyconditions i see there content-type header, if set say, audio/mp3 allow mp3 files , return error if file not mp3? i found previous question answers mention validating file size: s3 direct upload restricting file size , type you can specify content-type @ post request. you can specify @ signature, post must done content-type: { "expiration": "2007-12-01t12:00:00.000z", "conditions": [ {"acl": "public-read" }, {"bucket": "johnsmith" }, {"content-type: "audio/mp3"} ] } creating html form (using aws signature version 4) edit: @ previous question found, checking content-type.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
