    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。 ]ZKmf}A)1P  
    ,DsqKXSU  
    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: ~H!s{$.5  
    enableservice('AutomationServer', true) CnyCEIO-  
        enableservice('AutomationServer') 3;( ;'5|Z  
    ka? |_(  
    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 # 12  
    Z ? `  
    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: Mqc"  
    1. 在FRED脚本编辑界面找到参考. S\=j; Uem  
    2. 找到Matlab Automation Server Type Library b@j**O>[q)  
        3. 将名字改为MLAPP O* `v1>

         Y-\/Y*;cd  
    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。 ;/?M&rX

    2. 移动探测面对于前一聚焦面的位置。 nI4Kuz`dF  
    3. 在探测面追迹光线 @b[{.m U  
    4. 在探测面计算照度 )N h67P3X"  
    5. 使用PutWorkspaceData发送照度数据到Matlab :ad  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 W FVx7  
    7. 用Matlab画出照度数据 , 6 P:S7  
    8. 在Matlab计算照度平均值 (XW\4msB)I  
    9. 返回数据到FRED中 *6D0>F
