MATLAB 添加自定义的模块到simulink库浏览器

逝水lcc无痕

安装了matlab2014b后，突然发现Simulink Library Browser窗口中没有内容，找了一种方法添加进去，希望对有需要的朋友有所帮助！
1、创建库文件：打开Simulink Library Browser窗口。要建立Simulink库文件，首先启动Simulink工作窗口，单击菜单栏【File】下的【New】选项，选择【library】选项， 打开一个新的Library窗口界面，此时，用户可以将自己需要添加的一些模块加入到新的窗口中。然后保存为Own_efinition.mdl(所需要定义的库文件名称)。这样，就建立了一个 自定义的库文件。
2、在Matlab路径下创建存放库文件的路径，也即自定义的模块库在Library Browser下的显示位置。注意在Matlab中，每一个模块库文件所在的路径必须不同。
创建的Maltab路径是：Drogram FilesMATLABR2011btoolboxSimulinkSimulinkMyLibrary（根据自己的Matlab安装路径来确定）,其中MyLibrary为自定义的文件夹。
3、将第一步中建立的库文件拷贝到新建的Matlab路径下。在Matlab主窗口的【File】菜单栏下选择【Set Path】选项，然后单击【Add Folder】按钮，将新建的 路径添加进来,然后保存(Save)，退出(Close)。
4、要显示自定义的模块库，还需要拷贝slblocks.m函数到新建的路径下。在Matlab的命令窗口中输入：
>> which('slblocks.m', '-all')
>> open('Drogram FilesMATLABR2011btoolboxSimulinkSimulinkblocksslblocks.m')  

这样就可以打开slbocks.m文件模板，为了将自定义的模块库显示在Library Browser窗口下，需要对该程序进行修改。首先把slbocks.m文件拷贝到自定义库文件
同一目录下（即刚才创建的路径），然后打开该文件进行如下修改(红色为所作修改)，并保存：

如果还要在新建的模块库下面创建子模块库，需要把Subsystem模块加入到模块库中，打开Subsystem模块，删除所有内容（ports等元件），添加自己创建的模块
( {2 h3 R2 k6 g: b4 ?保存即可，然后重新打开Simulink Library Browser，按F5刷新，即可看到自定义的模块库和字模块库。
