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！
4 b( @  G: P- n0 [. V5 b1、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。
! X( W6 R* m+ t. u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。
6 |7 H0 S& s& j# L3、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：
) P7 [+ @- p% O+ H3 H>> which('slblocks.m', '-all')
1 H( O/ C) f9 D; o/ g% {1 V& r5 d7 E>> open('Drogram FilesMATLABR2011btoolboxSimulinkSimulinkblocksslblocks.m')  
9 C. ?4 s/ v- y6 L# i' c
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
1 Z3 N9 H' ^% U& _, M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：
function blkStruct = slblocks
%SLBLOCKS Defines the block library for a specific Toolbox or Blockset. % SLBLOCKS returns information about a Blockset to Simulink. The % information returned is in the form of a BlocksetStruct with the % following fields: %
% Name Name of the Blockset in the Simulink block library % Blocksets & Toolboxes subsystem.
% OpenFcn MATLAB expression_r(function) to call when you % double-click on the block in the Blocksets & Toolboxes % subsystem.
% MaskDisplay Optional field that specifies the Mask Display commands % to use for the block in the Blocksets & Toolboxes % subsystem.

5、再打开Simulink Library Browser，按F5刷新，即可看到自定义的模块库，展开后可以看到内部的自定义模块。那么用户可以方便地进行拖放模块，就可以使用 自定义的封装模块了。
2 a* q3 D7 z. u# A0 Z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
