    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。 [mPjP%{=@  
    LK@lpkX  
    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: #Z<a  
    enableservice('AutomationServer', true) *Otg*, \  
        enableservice('AutomationServer') ]TyisaT  
    ^tCd L@$AS  
    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 *>+,(1Fz  
    C|?o*fQ  
    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: /0eYMG+K=  
    1. 在FRED脚本编辑界面找到参考. W[}s o6  
    2. 找到Matlab Automation Server Type Library T0]*{k(FR  
        3. 将名字改为MLAPP ;Yg{zhJX~  
         K/}rP[H  
         P8?Fm`  
    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。 $e /^u[~:

    现在将脚本代码公布如下,此脚本执行如下几个步骤: }@^4,FKJ  
    1. 创建Matlab服务器。 v%RP0%%{s  
    2. 移动探测面对于前一聚焦面的位置。 kn/Ao}J74z  
    3. 在探测面追迹光线 9,^_<O@Q  
    4. 在探测面计算照度 MX ;J5(Ae  
    5. 使用PutWorkspaceData发送照度数据到Matlab EMc;^ d  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 DzheoA-+L'  
    7. 用Matlab画出照度数据 gy;+_'.j   
    8. 在Matlab计算照度平均值 oy;K_9\  
    9. 返回数据到FRED中 Dxk+P!!K
