matlab - set class variable in other function than constructor -


this question has answer here:

this basic question, did not find on internet. writing matlab class, has various class properties. setting of them (some input arguments, default). change 1 class variable in class method. not work (the variable gets deleted when out of function scope). best way solve this? put in constructor?

classdef myclass properties     matrix1     matrix2     matrix3 end methods     function obj = myclass()     obj.matrix1 = zeros(2)     obj.matrix2 = ones(3)     end      function obj = func(obj)     obj.matrix2 = 3*ones(3)     end     function obj = func2(obj)     obj.matrix3 = obj.matrix2 %this not work. matrix2 has original value, not 3*ones(3)     end end end

i call like

object = myclass()    object.func()    object.func2()

matlab supports both value-type , reference-type classes.

the way have defined class, inherently value type, means each function call uses copy of object, , not refer calling object's data.

to make class behave reference type, modify object's data require, inherit class handle.

do:

classdef myclass < handle     % else same here... end

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
