    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。 %A$5mi^  
    4x)etH^o  
    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: B@ xjwBUk  
    enableservice('AutomationServer', true) $SOFq+-T  
    enableservice('AutomationServer') F<+!28&h  
    1 O?bT,"b  
    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 v:1DNR4  
     Nt w?~%  
    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: V"Sa9P{y"  
    1. 在FRED脚本编辑界面找到参考.  81}JX  
    2. 找到Matlab Automation Server Type Library gr^T L1(  
    3. 将名字改为MLAPP j6:jN-z  
    x##0s5Qn  
    i< b-$9  
    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。 RD|DHio%

    1. 创建Matlab服务器。 "OO)m](w  
    2. 移动探测面对于前一聚焦面的位置。 jl"su:y  
    3. 在探测面追迹光线 LG+2?+tE"  
    4. 在探测面计算照度 =o5|W'>`  
    5. 使用PutWorkspaceData发送照度数据到Matlab EvKzpxCh  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 I'E7mb<2  
    7. 用Matlab画出照度数据 2;w`W58  
    8. 在Matlab计算照度平均值 &e6!/y&  
    9. 返回数据到FRED中 [0n[\& 0
