    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。 M='Kjc>e  
    AAcbY;  
    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: vKf=t&gqr  
    enableservice('AutomationServer', true) /+msrrpD  
    enableservice('AutomationServer') 6Y^o8R  
    |sz9l/,lG  
    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 |{T2|iJI  
    8vK&d>  
    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: k7*q.20  
    1. 在FRED脚本编辑界面找到参考. bSfQH4F  
    2. 找到Matlab Automation Server Type Library 5FxU=M1gF  
    3. 将名字改为MLAPP \ 714Pyy

    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。 Df (6DuW

    现在将脚本代码公布如下,此脚本执行如下几个步骤: \BL9}5y  
    1. 创建Matlab服务器。 <=Qk^Y2k  
    2. 移动探测面对于前一聚焦面的位置。 <X?F :?Mk  
    3. 在探测面追迹光线 5oS\uX|  
    4. 在探测面计算照度 eAMT72_  
    5. 使用PutWorkspaceData发送照度数据到Matlab 32yNEP{  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "|if<hx+  
    7. 用Matlab画出照度数据 KXJHb{?

    9. 返回数据到FRED中 h.*|4;
