    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。 T=\!2gt  
    >;nS8{2o  
    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: cwynd=^nC  
    enableservice('AutomationServer', true)  Q2\  
    enableservice('AutomationServer') sR*Nq5F#9  
    Z nXejpj)D  
    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 )|]Z>>%t  
    hz)9"B\S  
    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: 2 F?kjg,  
    1. 在FRED脚本编辑界面找到参考. {L0;{  
    2. 找到Matlab Automation Server Type Library G|9B )`S  
    3. 将名字改为MLAPP a$}mWPp+f

    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。 .nZ3kT`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: rsF:4G"%  
    1. 创建Matlab服务器。 i_U}{|j  
    2. 移动探测面对于前一聚焦面的位置。 =n0*{~r  
    3. 在探测面追迹光线 e.;M.8N#SQ  
    4. 在探测面计算照度 t(?<#KUB-  
    5. 使用PutWorkspaceData发送照度数据到Matlab `ROEV~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 UK3a{O[ 5  
    7. 用Matlab画出照度数据 &" h]y?Q  
    8. 在Matlab计算照度平均值 U9ZbVjqv@
