    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 aD%")eP%&  
    eQzSWn[  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: 9)mJo(  
    enableservice('AutomationServer', true) xr.fZMOh4  
    enableservice('AutomationServer') IjNE1b$  
    Av+R~&h  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 m#'u;GP]k  
    $Fr$9 jq&  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: INcJXlv  
    1. 在FRED脚本编辑界面找到参考. ;QW)tv.y  
    2. 找到Matlab Automation Server Type Library ]6 }|X#_  
    3. 将名字改为MLAPP 9> [ $;>

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 ]]9eUw=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ?XW+&!ar  
    1. 创建Matlab服务器。 H |75,!<  
    2. 移动探测面对于前一聚焦面的位置。 W99Fb+$I  
    3. 在探测面追迹光线 =}_c=z?UY  
    4. 在探测面计算照度 W\FKA vS  
    5. 使用PutWorkspaceData发送照度数据到Matlab #WfJz}P,!  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 `Mp]iD {  
    7. 用Matlab画出照度数据 vmW4a3  
    8. 在Matlab计算照度平均值 $6ITa}o  
    9. 返回数据到FRED中 qdO^)uJJ
