    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。 q0mOG^  
    W_M'.1 t  
    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: u0)7i.!M  
    enableservice('AutomationServer', true) [dX`K`k  
        enableservice('AutomationServer') *4Fr&^M\  
    mABe'"8  
    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  l]!9$  
    EpPf _ \o  
    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: `s#Hq\C  
    1. 在FRED脚本编辑界面找到参考. 's x\P[a  
    2. 找到Matlab Automation Server Type Library we7c`1E  
        3. 将名字改为MLAPP KU9Z"9#  
         XkmQBV"  
         NmIHYN3  
    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。 J'&# mDU

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Z{NC9  
    1. 创建Matlab服务器。 t=euE{c  
    2. 移动探测面对于前一聚焦面的位置。 2GmpCy`L"  
    3. 在探测面追迹光线 `<"m%>  
    4. 在探测面计算照度 @JkK99\(>9  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;,'igdold  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 1t[j"CG(o  
    7. 用Matlab画出照度数据 V_n<?9^4  
    8. 在Matlab计算照度平均值 Pi2|  
    9. 返回数据到FRED中 ,SlN zR
