    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。 XD}_9p  
    [i7)E]*oTA  
    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: V bOLTc  
    enableservice('AutomationServer', true) Vz]=J;`Mz  
    enableservice('AutomationServer') {W<-f?  
    Ai18]QD-  
    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 FaE orQ

    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: ,&] ` b#Rc  
    1. 在FRED脚本编辑界面找到参考. wlg#c6#q  
    2. 找到Matlab Automation Server Type Library @0,dyg<$>  
    3. 将名字改为MLAPP cV,Dl`1r  
     q)+ n2FM  
    r$Y!Y#hwQ  
    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。 WI_mJ/2

    1. 创建Matlab服务器。 Zb;$ZUWQX  
    2. 移动探测面对于前一聚焦面的位置。 :-" jK w  
    3. 在探测面追迹光线 g8A{aHb1}  
    4. 在探测面计算照度 >[4|6k|\x  
    5. 使用PutWorkspaceData发送照度数据到Matlab l>Ja[`X@  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4^_Au^8R(  
    7. 用Matlab画出照度数据 eh4"_t
