    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。 U5mec167  
    C]UBu-]#S  
    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: NF=FbvNe  
    enableservice('AutomationServer', true) to Ei4u)m  
        enableservice('AutomationServer') `+b>@2D_  
    q>&F%;q1]  
    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 3 uwZ#   
    P9J3Ii!  
    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: !l'Az3'J|  
    1. 在FRED脚本编辑界面找到参考. 9/w'4bd  
    2. 找到Matlab Automation Server Type Library <p(&8P  
        3. 将名字改为MLAPP :=04_5 z  
         9frx60  
         0_bt*.w I+  
    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。 /qF7^9LtaY

    2. 移动探测面对于前一聚焦面的位置。  $J mL)r  
    3. 在探测面追迹光线 : o$ R@l  
    4. 在探测面计算照度 |6B:tw/.  
    5. 使用PutWorkspaceData发送照度数据到Matlab O#A1)~  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 bWv6gOPR3  
    7. 用Matlab画出照度数据 -mZo`  
    8. 在Matlab计算照度平均值 q 9qmz[  
    9. 返回数据到FRED中 $XFG1?L!
