    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。 D Q={  
    MNe/H\  
    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: + XBF,<P  
    enableservice('AutomationServer', true) R-ek O7z  
        enableservice('AutomationServer') Ucy=I$"  
    )_! a:  
    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 cL4Go,)w  
    sXPva@8_  
    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: ol_\ "  
    1. 在FRED脚本编辑界面找到参考. s1Wn.OGR4  
    2. 找到Matlab Automation Server Type Library 8b 7I\J`  
        3. 将名字改为MLAPP .0U[n t6  
         z@19gD#8  
         R7z @y o  
    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。 1qn/*9W}=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 5W fZd  
    1. 创建Matlab服务器。 w0$+v/  
    2. 移动探测面对于前一聚焦面的位置。 ^5~x*=_  
    3. 在探测面追迹光线 PEjd  
    4. 在探测面计算照度 gk8 v{'0Er  
    5. 使用PutWorkspaceData发送照度数据到Matlab k-^^Ao*@  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 4,QA {v  
    7. 用Matlab画出照度数据 V:5aq.o!  
    8. 在Matlab计算照度平均值 P;gd!Yl<-  
    9. 返回数据到FRED中 a[zVC)N0
