Ubuntu系统中gVim的基本安装与配置教程
安装:1. 在www.vim.org上 下载 源码包 vim-7.4.tar.bz2
2. 开发库libncurses5-dev安装 :
复制代码
代码如下:
sudo apt-get install libncurses5-dev3. 解压 tar jxvf vim-7.4.tar.bz2,进入vim/src:
复制代码
代码如下:
./configure --with-features=huge --enable-pythoninterp=yes --enable-gui=gnome2 --enable-cscope --enable-fontset --enable-perlinterp --enable-rubyinterp --with-python-config-dir=/usr/lib/python2.6/config4.
复制代码
代码如下:
make sudo make install5. 这样vim就安装完成,源码ssm框架整合源码下面安装gvim:
复制代码
代码如下:
sudo apt-get install vim-gnomegvim配置文件.vimrc中的源码一些基本配置讲解:

通过使用: commands命令,告诉我们文件的源码哪一行被改变过
set report=0
启动的时候不显示那个援助索马里儿童的提示

set fillchars=vert:\ ,源码stl:\ ,stlnc:\
高亮显示匹配的括号
set showmatch
匹配括号高亮的时间(单位是十分之一秒)
set matchtime=5
光标移动到buffer的顶部和底部时保持3行距离
set scrolloff=3
为C程序提供自动缩进
set smartindent
只在下列文件类型被侦测到的时候显示行号,普通文本文件不显示

如何用matlab中的envelope函数画包络图。
下面是源码pptv云播源码一系列关于MATLAB的包络线的程序:
%这是定义了一个函数:
function [up,down] = envelope(x,y,interpMethod)
%ENVELOPE gets the data of upper and down envelope of the known input (x,y).
%
% Input parameters:
% x the abscissa of the given data
% y the ordinate of the given data
% interpMethod the interpolation method
%
% Output parameters:
% up the upper envelope, which has the same length as x.
% down the down envelope, which has the same length as x.
%
% See also DIFF INTERP1

% Last Revision: -Mar-.

% $Revision: 1.1 $ $Date: 3// : AM $
if length(x) ~= length(y)
error('Two input data should have the same length.');
end
if (nargin < 2)|(nargin > 3),
error('Please see help for INPUT DATA.');
elseif (nargin == 2)
interpMethod = 'linear';
end
% Find the extreme maxim values
% and the corresponding indexes
%----------------------------------------------------
extrMaxValue = y(find(diff(sign(diff(y)))==-2)+1);
extrMaxIndex = find(diff(sign(diff(y)))==-2)+1;
% Find the extreme minim values
% and the corresponding indexes
%----------------------------------------------------
extrMinValue = y(find(diff(sign(diff(y)))==+2)+1);
extrMinIndex = find(diff(sign(diff(y)))==+2)+1;
up = extrMaxValue;
up_x = x(extrMaxIndex);
down = extrMinValue;
down_x = x(extrMinIndex);
% Interpolation of the upper/down envelope data
%----------------------------------------------------
up = interp1(up_x,up,x,interpMethod);
down = interp1(down_x,down,x,interpMethod);
