如何diy一款MATLAB进度条？

0效果

1来由

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=1:1000A(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，我就想研究以下其属性来想办法能否对其修饰，于是我进行了一波 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：

所以说总结来说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。

2函数用法

写了以下几个进度条函数（四种风格）：

waitBar_SL1.m
waitBar_SL2.m
waitBar_SL3.m
waitBar_SL4.m

基本用法like this:

bar=waitBar_SL1(0,'loading ...');  % 初始化len=500;
for i=1:lenA(i)=rand(); % 这句一点用都没有，只是假装这是工程的一部分str=['progress - ',num2str(round(i/len*100)),'%']; % 显示的文本waitBar_SL1(bar,i/len,str);
end
