1.使用效果
首先我有个程序需要用到进度条，我首先试了一下MATLAB自带的进度条：
bar=waitbar(0,'读取数据中...'); % waitbar显示进度条
for i=1:1000
A(i)=rand();
str=['计算中...',num2str(100*i/1000),'%']; % 显示的文本
waitbar(i/1000,bar,str)
end
但是这样的进度条显得冷冰冰的，我就想研究一下其属性来想办法看能否对其修饰。
以前的版本系统自带的进度条可以通过。
set(findobj('type','patch'),'facecolor','b')
这样的方式改变颜色，但是慢慢的随着版本更新，这样的修改方式已经不行了，于是我便尝试查看新版本 waitbar 是怎样刷新进度条的，我进行了一波 open waitbar 发现这个函数就只是创建了figure和axes并不断更新图像：
其中更新图像主要依赖一个名为 uiwaitbar 的函数：
于是我想当然的试了一下 open uiwaitbar 结果发现打不开。。。
于是我根据 waitbar.m 的位置顺藤摸瓜的在：toolbox\matlab\uitools\private
路径找到了 uiwaitbar.p 文件，啊加密文件，那没事了嗷：
虽然是加密文件，但我们还是通过换着参数调用发现这个函数可能需要用到一些png或者css文件：
不过本人css用的确实不够熟，同时也比较难看出加密文件到底是怎么调用css文件的，但是总结来说waitbar就只是一个不断刷新图像的figure而已，我们自己写的话甚至可以不用css或者png，直接用自带的画图函数都可以。
3.函数用法写了以下几个进度条函数（四种风格）：
waitBar_SL1.m(仅支持英文)
waitBar_SL2.m
waitBar_SL3.m
waitBar_SL4.m
基本用法like this:
bar=waitBar_SL2(0,'loading ...'); % 初始化
for i=1:1000
A(i)=rand();
str=['precess - ',num2str(round(i/10)),'%']; % 显示的文本
waitBar_SL2(bar,i/1000,str);
end
