    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。 'Sk-L 5  
    ebv"`0K$  
    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: #u]'3en  
    enableservice('AutomationServer', true) zw ,( kv  
    enableservice('AutomationServer') d x52[W  
    5|:t$  
    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 !N"Y  
    i?^lEqy[  
    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: J A!?vs  
    1. 在FRED脚本编辑界面找到参考. e:`d)GE  
    2. 找到Matlab Automation Server Type Library $e#V^dph  
    3. 将名字改为MLAPP &-R(u}m-F  
    ^VL",Nt  
    ip)gI&kN`z  
    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。 J)I|Xot

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 9lU"m_ QT4  
    1. 创建Matlab服务器。 lJ>OuSd  
    2. 移动探测面对于前一聚焦面的位置。 <36z,[,kZ@  
    3. 在探测面追迹光线 a|Yry  
    4. 在探测面计算照度 #]SiS2lM#  
    5. 使用PutWorkspaceData发送照度数据到Matlab LWX,u  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 mto=_|gn  
    7. 用Matlab画出照度数据 4;;K1< 1  
    8. 在Matlab计算照度平均值 t?l0L1;  
    9. 返回数据到FRED中 Lkf}+aY
