    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。 _Ik?WA_;  
    W?.469yy  
    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: EpMxq7*  
    enableservice('AutomationServer', true) Mp|Jt  
    enableservice('AutomationServer') Y_:jc{?  
    %0C [v7\  
    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 $5JeN{B  
    i3N{Dt  
    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: z0<E3t  
    1. 在FRED脚本编辑界面找到参考. H dqB B   
    2. 找到Matlab Automation Server Type Library {k_\1t(/  
    3. 将名字改为MLAPP &`l\Q\_[@  
    uv/\1N;V3  
    znsQ/[  
    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。 nwKp8mfP

    1. 创建Matlab服务器。 vu*e*b$}  
    2. 移动探测面对于前一聚焦面的位置。 &<98n T  
    3. 在探测面追迹光线 5 :IDl1f5  
    4. 在探测面计算照度 F%|P#CaB  
    5. 使用PutWorkspaceData发送照度数据到Matlab *zrGrk:l  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8>e YM  
    7. 用Matlab画出照度数据 HfVHjF)  
    8. 在Matlab计算照度平均值 @Z ==B%`  
    9. 返回数据到FRED中 9m)$^U>oz
