容易忘记的小知识点: Matlab程序首行程序: clear:close all:clc:程序运行开始最好清理下之前残留的各种数据,不然matlab可能会出错. clear(清理变量空间),close all(关掉所有显示的图像figure),clc(清理命令窗口中的显示) Matlab程序换行(一个空格加上3个.即 ...然后直接下一行就可以继续写代码) Matlab下程序计时 如下:tic和toc可以在程序中使用多个,计算各个程序字块的运行时间.还可以嵌套使用... tic;%计时开始 %%

Fig是Docker的应用编排工具,主要用来跟 Docker 一起来构建基于 Docker 的复杂应用,Fig 通过一个配置文件来管理多个Docker容器,非常适合组合使用多个容器进行开发的场景. 说明:目前Fig已经升级并更名为Compose.Compose向下兼容Fig. 所以学完fig再去看compose也是可以的. 应用编排工具使得Docker应用管理更为方便快捷. Fig网站:http://www.fig.sh/ 安装Fig: # 方法一: curl -L https://github

这篇文章是上篇文章”Expdp 导数错误 ORA-00832”的延续,前几天工作比较忙.累,直到今天才整理发出来.这个数据库实例的参数设置比较诡异其实是有原因的,由于这台数据库服务器系统是32位,数据库也是32位的.对于绝大部分32位系统上的32位数据库,SGA最大的设置都不能超过2G,有的系统最大值甚至不能超过1.7G左右.DBA为了让内存充分利用,不至于浪费内存资源,于是想让SGA_MAX_SIZE最大化,对数据库相关参数做了调整,设置参数USE_INDIRECT_DATA_BUFFERS为

Today, I have to create a dll project(called my.sln), the dllmain.cpp/.h/ is already in another project(called A.sln), I only have to update the included lib file in my dll project. So I create a new win32 project, which is an empty dll project. Here

下午从生产库导出了一份表结构,用来测试一些问题,由于生产库连接着其他用户下的表所以通过视图在本地模拟一下,于是创建视图: create or replace view csews as select * from order_list; 但是出现ORA-00955: name is already used by an existing object的错误, 上网查了下说是数据库中有了同名对象,于是查询 select * from all_objects where object_name='c

今天Linux服务器机子重启了下,Oracle启动不起来,提示:解决ORA-00824: cannot set sga_target due to existing 看了很多解决方法,发现下面这个特别好,特别简单 转:http://blog.chinaunix.net/uid-22448653-id-388649.html 按照这种思路: 1.我们完全可以先用pfile的配置参数启动数据库实例 2.通过pfile重建spfile文件(create spfile from pfile) 3.关闭数

案例:之前跑过的程序 已经生成了多个matlab图,现在需要进行合并到一个图中. 解决方案,利用图像句柄把figure图像中的参数读入到内存中,然后重新subplot绘制. 程序如下: clc;clear; open(‘./test_1.fig’) figure_info=findall(gcf,’type’,'line’); xdata1 = get(figure_info,’xdata’); ydata1 = get(figure_info,’ydata’); color1 = get(fi
