matlab 程序运行很慢，怎么改进？
提高matlab程序运行速度，可以用以下方法：
1、更改MATLAB启动快捷方式
在缺省配置下，MATLAB有一个启动闪屏，去掉它可以节省一定的内存消耗，从而加快启动。
在MATIJAB启动快捷方式后添加命令行参数 一nos－plash”即可_去掉闪屏。
缺省配置 MATLAB会启动虚拟机，这会消耗大量内存。添加命令行参数"-nojvm”可禁用JAVA虚拟机。
MATLAB启动快捷方式命令形如：
"％MATLABROOT％＼bin＼win32\matlab.exe -nosplash -nojvm”。
经过以上配置，MATLAB启动和运行速度会得到大幅提升。
注意：禁用JAVA虚拟机后，MATLAB中有些功能，诸如：调试功能、可视化界面设计功能不能使用，但大多数其它功能可正常运行。如果使用的功能需要JAVA虚拟机支持，启动时将命令行参数 一nojvm 去掉即可。
2、更改MATLAB搜索路径
MATLAB启动时会添加搜索路径。如果安装了多个工具箱，搜索路径会很多。过多的搜索路径除了减缓启动速度外，还会影响MATLAB执行效率。因为MATLB执行程序时会在这些路径中寻找M文件。而实际上我们不会为完成某个任务使用所有的工具箱。为提高启动和运行速度，可以修改pathdef．m文件，将暂时不用的工具箱和其它搜索路径注释掉(MATLAB程序以％为注释标识)，从而加快启动和运行。

java程序设计帮我分析一下每句话的意思好吗
说一下大致的吧：
1.import引入包，下面会用到
2.public class HandleMove extends JPanel implements
MouseListener,ActionListener {
//创建HandleMove类并继承JPanel并实现MouseListener,ActionLister接口
2. Point [][] point;
int spendTime=0;
javax.swing.Timer recordTime;
JTextField showTime;
VerifySuccess verify;
//声明变量，各个类型地，这里的变量类型就是引入包import
javax.swing.*; 这里的
3.HandleMove(){
recordTime=new javax.swing.Timer(1000,this);
showTime=new JTextField(16);
showTime.setEditable(false);
showTime.setHorizontalAlignment(JTextField.CENTER);
showTime.setFont(new Font("楷体_GB2312",Font.BOLD,16)); //设
置字体
JLabel hitMess=new JLabel("用鼠标单击方块",JLabel.CENTER);//
设置JLabel标签
hitMess.setFont(new Font("楷体_GB2312",Font.BOLD,18)); //设置
字体
add(hitMess); //添加到Jpanel面板
add(showTime); //添加到Jpanel面板
setBackground(Color.cyan); //设置面板背景颜色
}
//定义构造器,并创建各个组件
4.下面就是创建各类方法
用于实现各个功能点
Avalanche (Java) 歌词
歌曲名:Avalanche (Java)

专辑:Dansez Avec Jo Privat
Manafest - Avalanche
Get me out, (out) get me out (out)
PREACHER, PREACHER what you got for me save my soul
See beneath, and clip my wings I'm not an angel
I try and try to be good, I've lied with pride I'm a crook
Turn the lights down, burning up the night now
Sign my life out, I'm sick of living here yo
If you can help choir boy ring the church bells
I'd turn back if I could, erase the pain if I could
But I'm an animal and I don't know if I can
Hey!!
Cause I'm the prodigal man of this avalanche
I'm going down, I'm going down, down
Hey!!!!
And if you turn me in
I'll confess my sins
I'm going down, I'm going down, down
Before I'm six feet deep
I'm washing my hands clean
Just get me out of this avalanche
You scared the junk-crap out of me man
The Ghost Rider, hold my soul tighter
Jehovah take the ropes I'm a
Fly a plane out of the atmosphere
I've attacked this fear
This scar still here
I'm going on to the end
I'm holding out to a friend
I'm going I'm going
I don't care
I cursed a lot
The worse, the black sheep of the lot
Christopher Scott prepare to meet God
Hey!!
Cause I'm the prodigal man of this avalanche
I'm going down, I'm going down, down
Hey!!!!
And if you turn me in
I'll confess my sins
I'm going down, I'm going down, down
Before I'm six feet deep
I'm washing my hands clean
Just get me out of this Avalanche
Get me out, OUT
Get me out, OUT
Just get me out of this avalanche
Get me out, OUT
Get me out, OUT
Just get me out of this...
You guided me when I was
Blind with pride a right off
Knocked me off my saddle
Sabotaged and overshadowed
Watched you chase a man down
Watched you raise a man out
Mercy on me, forever I'm free
Hey!!
Cause I'm the prodigal man of this avalanche
I'm going down, I'm going down, down
Hey!!!!
And if you turn me in
I'll confess my sins
I'm going down, I'm going down, down
Before I'm six feet deep
I'm washing my hands clean
Just get me out of this Avalanche
Get me out, OUT
Get me out, OUT
Just get me out of this avalanche
Get me out, OUT
Get me out, OUT
Just get me out of this...
