    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。 0t!ZMH  
    bq7+l4CGTv  
    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: BPkMw'a:  
    enableservice('AutomationServer', true) (Yj6 |`  
    enableservice('AutomationServer') i%133in  
    qE2<vjRg  
    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 zk$h71<{.

    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:  $Z &6  
    1. 在FRED脚本编辑界面找到参考. <IR@/b!,  
    2. 找到Matlab Automation Server Type Library LeN }Q  
    3. 将名字改为MLAPP 8i "CU:(  
    X#axCDM-  
    ,'c%S|]U7  
    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。 Z%o.kd"

    60~*$`  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: umP nw  
    1. 创建Matlab服务器。 !m\By%(  
    2. 移动探测面对于前一聚焦面的位置。 *><j(uz!  
    3. 在探测面追迹光线 / w dvm4  
    4. 在探测面计算照度 Z=-#{{bv  
    5. 使用PutWorkspaceData发送照度数据到Matlab N''xdz3Z  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 1<x5{/CZ  
    7. 用Matlab画出照度数据 kN 2mPD/  
    8. 在Matlab计算照度平均值 dh]Hf,OLF  
    9. 返回数据到FRED中 u@D5SkT
