    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。 FwGMrJW  
    6PI-"He  
    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: cYEe`?*  
    enableservice('AutomationServer', true) Pi|oO-M  
    enableservice('AutomationServer') 6Bm2_B  
    OKq={l  
    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 /2!"_?<L

    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: X{riI^(  
    1. 在FRED脚本编辑界面找到参考. ?|9$o/Q}  
    2. 找到Matlab Automation Server Type Library D+  **o  
    3. 将名字改为MLAPP {VE$i2nC8  
    }UWRH.;v  
    &9'JHF!l  
    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。 5{|\h}

    现在将脚本代码公布如下,此脚本执行如下几个步骤: NeyGIEP  
    1. 创建Matlab服务器。 WH$ Ls('  
    2. 移动探测面对于前一聚焦面的位置。 B1Iq:5nmoS  
    3. 在探测面追迹光线 t`mLZ <X  
    4. 在探测面计算照度 $bKa"T*  
    5. 使用PutWorkspaceData发送照度数据到Matlab |"Oazll  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ZvO:!u0+"  
    7. 用Matlab画出照度数据 9?W38EF
