    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。 E!=Iz5  
    }LoMS<O-[  
    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: LMLrH.  
    enableservice('AutomationServer', true) 0W)|n9  
    enableservice('AutomationServer') G#1W":|`  
    [<wpH0lNoy  
    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 5? f!hB|6  
    \GZ|fmYn  
    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: nL]eGC  
    1. 在FRED脚本编辑界面找到参考. R.YUUXT  
    2. 找到Matlab Automation Server Type Library w8`B}Dr23  
    3. 将名字改为MLAPP D&OskM60

    w,OPM}) il  
    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。 3XDuo|(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: mRxeob  
    1. 创建Matlab服务器。 v]T?xo~@'  
    2. 移动探测面对于前一聚焦面的位置。 N7_(,Gu*R  
    3. 在探测面追迹光线 j_z@VT}y  
    4. 在探测面计算照度 CXTt N9N9  
    5. 使用PutWorkspaceData发送照度数据到Matlab VeOM `jy  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 B) dG:~  
    7. 用Matlab画出照度数据 8= g~+<A  
    8. 在Matlab计算照度平均值 & s:\t L  
    9. 返回数据到FRED中 Y3SV6""y/
