    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。 Vz @2_k   
    !9p;%Ny`  
    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: d":GsI?3  
    enableservice('AutomationServer', true) OAw- -rl  
        enableservice('AutomationServer') z}z 6Vg  
    e !2SO*O  
    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 ~H4wsa39  
    M%(^GdI#Vf  
    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: "\`>Ll  
    1. 在FRED脚本编辑界面找到参考. E>I\m!ue  
    2. 找到Matlab Automation Server Type Library UYw=i4J'  
        3. 将名字改为MLAPP ~;S  
         -g\;B  
         "&Rt&S  
    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。 K{ED mC

    现在将脚本代码公布如下,此脚本执行如下几个步骤: fPBJ%SZ  
    1. 创建Matlab服务器。 U]AJWC6  
    2. 移动探测面对于前一聚焦面的位置。 "zZ Z h  
    3. 在探测面追迹光线 A~)#  
    4. 在探测面计算照度 h"3Mj*s  
    5. 使用PutWorkspaceData发送照度数据到Matlab sD ,=_q@  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ^g SZzJ5  
    7. 用Matlab画出照度数据 XT%\Ce!  
    8. 在Matlab计算照度平均值 f1w_Cl  
    9. 返回数据到FRED中 Q5xQ5Le
