    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。 @sVBG']p  
    ;m\E9ple  
    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: 7JujU.&{6  
    enableservice('AutomationServer', true) o;"!#Z 1SJ  
    enableservice('AutomationServer') @x)z" )>  
    1 @/+ c  
    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 %o5GD

    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: 1j}o. 0\  
    1. 在FRED脚本编辑界面找到参考. k(s3~S2h  
    2. 找到Matlab Automation Server Type Library bO-8<IjC_3  
    3. 将名字改为MLAPP h.DQ6!?;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。 B64%| S

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 0O[q6!&]  
    1. 创建Matlab服务器。 n] &fod  
    2. 移动探测面对于前一聚焦面的位置。 )]v vp{  
    3. 在探测面追迹光线 %!WQ;(  
    4. 在探测面计算照度 '*K/K],S]  
    5. 使用PutWorkspaceData发送照度数据到Matlab +^`c" qJo  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !I:6L7HdwB  
    7. 用Matlab画出照度数据 ~jJu*s$?  
    8. 在Matlab计算照度平均值 }Za[<t BWS  
    9. 返回数据到FRED中 z. 7 UfLV9
