    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。 +FlO_=Bu  
    5>"X?U}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: P4dhP-t  
    enableservice('AutomationServer', true) De:| T8&  
    enableservice('AutomationServer') UN Kr FYl  
    L[.RV*sL  
    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 4A~1Z,"%v(  
    f-l(H="e  
    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+qrsT/?L  
    1. 在FRED脚本编辑界面找到参考. LIMPWw g  
    2. 找到Matlab Automation Server Type Library Jz6zJKcA  
    3. 将名字改为MLAPP jun$C Y4

    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。 _';oT*#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ^Jdji:  
    1. 创建Matlab服务器。 hy{1Ea/T  
    2. 移动探测面对于前一聚焦面的位置。 #u<n .  
    3. 在探测面追迹光线 6,UW5389  
    4. 在探测面计算照度 :7jDgqn^|i  
    5. 使用PutWorkspaceData发送照度数据到Matlab }  cQ` L  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 `KUl XS(  
    7. 用Matlab画出照度数据 "3X~BdH&J  
    8. 在Matlab计算照度平均值 x72T5.  
    9. 返回数据到FRED中 tg' 2 v/
