    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。 "8uNa  
    N2 3:+u<)E  
    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: + \%]<YO  
    enableservice('AutomationServer', true) Q[#8ErUY  
    enableservice('AutomationServer') S?`0,F  
    7neJV  
    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 stfniV  
    qHgtd+ I  
    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: B%u[gNZ  
    1. 在FRED脚本编辑界面找到参考. MC,Qv9m  
    2. 找到Matlab Automation Server Type Library V.$tq  
    3. 将名字改为MLAPP 3mYW]  
    '?m2|9~  
    ~vpF|4Zn5  
    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。 SD*q+Si,1U

    现在将脚本代码公布如下,此脚本执行如下几个步骤: .H M3s  
    1. 创建Matlab服务器。 3'6 UvAXFH  
    2. 移动探测面对于前一聚焦面的位置。 x.t&NP^V)  
    3. 在探测面追迹光线 Md>C!c  
    4. 在探测面计算照度 j+-`P5  
    5. 使用PutWorkspaceData发送照度数据到Matlab V D7^wd9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 v4E=)?  
    7. 用Matlab画出照度数据 cs\=8_5  
    8. 在Matlab计算照度平均值 03|nP$g  
    9. 返回数据到FRED中 Z R=[@Oi
