    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。 B ,epzI  
    G*P#]eO  
    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: 81 sG  
    enableservice('AutomationServer', true) '$%l7  
        enableservice('AutomationServer') Z}Ft:7   
    @r/n F5  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 ]-/VHh  
    ckE-",G  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: L0WN\|D  
    1. 在FRED脚本编辑界面找到参考. 'AS|ZRr/  
    2. 找到Matlab Automation Server Type Library <B6H. P =  
        3. 将名字改为MLAPP Qjv}$`M  
         [:SWi1cK2  
         QE`bSI  
    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。 .jWC$SVR

    现在将脚本代码公布如下,此脚本执行如下几个步骤: (V67`Z )  
    1. 创建Matlab服务器。 sN01rtB(UT  
    2. 移动探测面对于前一聚焦面的位置。 *mvlb (' &  
    3. 在探测面追迹光线 ={@6{-tl  
    4. 在探测面计算照度 JO6)-U$7UG  
    5. 使用PutWorkspaceData发送照度数据到Matlab +}os&[S  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 0{}8(  
    7. 用Matlab画出照度数据 <k'h:KB?`  
    8. 在Matlab计算照度平均值 >V8-i`  
    9. 返回数据到FRED中 K} X&AJ5A
