    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。 (kLaXayn  
    ;Sivu-%  
    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: LIcc0w3  
    enableservice('AutomationServer', true) z,TH}s6  
    enableservice('AutomationServer') Qfm$q~`D^W  
    A7X a  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Zt!#KSF7%  
    c#N4XsG,  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ZG^<<V$h  
    1. 在FRED脚本编辑界面找到参考. eG,x\  
    2. 找到Matlab Automation Server Type Library  `M I;.t  
    3. 将名字改为MLAPP $t;:"i>

    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。 ,j*9)

    1. 创建Matlab服务器。 nEsD+ }E?  
    2. 移动探测面对于前一聚焦面的位置。 G+<XYkz*  
    3. 在探测面追迹光线 NuQ!huh  
    4. 在探测面计算照度 7 XxZF43  
    5. 使用PutWorkspaceData发送照度数据到Matlab *-9i<@|(U^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 C.S BJ  
    7. 用Matlab画出照度数据 EVqW(|Xg

    9. 返回数据到FRED中 sv=U^xI
