问题 So I need to write a program which uses a recursive function to store the value of input arguments in the order they were made. e.g. If my function is [f trace]=fibo_trace(6,[]) it should return [f trace]=fibo_trace(6,[]) f= 8 trace= 6 4 2 3 1 2 5 3 1 2 4 2 3 1 2 With trace being the values with which the recursive call is being initialized and f being the 6th element in the fibonacci series. Here is my code function [f,trace] = fibo_trace(n,v) persistent ptrace; % must specify persistent v=n

Closed 5 years ago . Improve this question I need really fast and persistent cache for my web crawler. It doesnt need to be as fast as ConcurrentSkipListSet in Java, but definitely it cannot be MySQL with hash-index based table, which i tried. After 1m+ of records it takes like 80% of processor time. Does

问题 We're developing a Play 2.4 application (Java API). For dev purposes, we'd like to use a persistent H2 database with DB file path relative to the project root directory. In How to use a persistent H2 database in the Play Framework instead of in-memory there was solution for Play 2.0: db.default.url="jdbc:h2:file:data/db" However, with Play 2.4 this doesn't seem to work but I get error message with the following exception at the bottom: Caused by: org.h2.jdbc.JdbcSQLException: A file path that

问题 I am wondering if there is a way that I can manage different layouts based on button clicks in PySimple GUI. I am just starting off using this framework and I want to find the best way of navigating menus. Doesn't have to be using different layouts but this just struck me of the most intuitive way of doing it. I was thinking like maybe having a list of layouts that get pushed to the top when a certain submenu button is selected. layouts = [layout1, layout2, layout3, layout4] Or maybe start

问题 I have a BlackBerry application that starts (App load) with a Registration screen when the App is first installed. Later, the App will load with the home screen. Registration screen only appears on first load. I am achieving this by storing a boolean value in PersistentStore . If the value exists, then Registration screen will not appear. PersistentStoreHelper.persistentHashtable.put("flagged",Boolean.TRUE); PersistentStoreHelper.persistentObject.commit(); UiApplication.getUiApplication()
