利用Matlab复刻举牌加油小人生成器
突然发现cla函数也可以应用到app designer控件上，因而对部分内容做出更改。
手痒，用matlab app designer复刻了一款举牌加油小人生成器，效果如下：
该程序可以生成正方形和长方形举牌小人，并且可以自己设置背景颜色(点击那些有颜色的小框框),点击绿色旋转按钮可以刷新生成的图片。
目前需要存图还是需要通过uiaxes自带的toolbar(下图右上角所示):
使用该程序需要小人的素材包，我已经将素材整理为materials.mat文件，网盘下载链接如下：

提取码：1234
使用时需要把materials.mat和m文件放在同一文件夹

若matlab是版本为R2016a以后，R2019a之前,会因为uiimage未被推出而无法正常使用，可以尝试以下代码，该代码依旧需要materials.mat和m文件在同一文件夹：
