    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。 M+&eh*:z:  
    @Oc}\Rg  
    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: 8w@jUGsc  
    enableservice('AutomationServer', true) B(vz$QE,$r  
    enableservice('AutomationServer') E":":AC#  
    I:2jwAl  
    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 [~r $US  
    rN!9&  
    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: }j<_JI  
    1. 在FRED脚本编辑界面找到参考. i~PZvxt  
    2. 找到Matlab Automation Server Type Library 21J82M  
    3. 将名字改为MLAPP xx2:5  
    vH:+  
    C&K(({5O  
    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。 L$07u{Q  
    7^}Z%c

    O#Ax P}  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: HE .Dl7 {  
    1. 创建Matlab服务器。 gYIYA"xN`  
    2. 移动探测面对于前一聚焦面的位置。 C4d1*IQk  
    3. 在探测面追迹光线 g<jK^\e W  
    4. 在探测面计算照度 K1:)J.ca_  
    5. 使用PutWorkspaceData发送照度数据到Matlab '$nGtB5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 leqSS}KU+  
    7. 用Matlab画出照度数据 $R}iL  
    8. 在Matlab计算照度平均值 Jx[e{o)o  
    9. 返回数据到FRED中 H ;}ue
