    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。 ]r6BLZ[%  
    *M&VqG4P9w  
    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: N`<4:v[P  
    enableservice('AutomationServer', true) x #tu  
    enableservice('AutomationServer') g7 Md  
    {nQ)4.e6  
    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 )0U3w#,JQ  
    5Hwo)S]r  
    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@}B:}2  
    1. 在FRED脚本编辑界面找到参考. v=*Bb3dt  
    2. 找到Matlab Automation Server Type Library +-aU+7tu  
    3. 将名字改为MLAPP E +Ujpd  
    B]|6`UfB  
    7O+Ij9+{n  
    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。 Z[k#AgC)

    现在将脚本代码公布如下,此脚本执行如下几个步骤: VqD[G<|9T  
    1. 创建Matlab服务器。 Cgz&@@j,]  
    2. 移动探测面对于前一聚焦面的位置。 lHcZi  
    3. 在探测面追迹光线 .lvI8Jf~X  
    4. 在探测面计算照度 vr{'FMc  
    5. 使用PutWorkspaceData发送照度数据到Matlab N4a`8dS|  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 B0)`wsb_  
    7. 用Matlab画出照度数据 [arTx ^  
    8. 在Matlab计算照度平均值 BEXQTM3])I  
    9. 返回数据到FRED中 F<yy>Wf
