    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。 ,*}g r  
    X-2S*L'  
    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: A](}"Pi!n  
    enableservice('AutomationServer', true) 'm p{O  
    enableservice('AutomationServer') dW=D]  
    5KPPZmO  
    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 Zn*CJNB

    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: J'Mgj$T $  
    1. 在FRED脚本编辑界面找到参考. ^>R|R1&  
    2. 找到Matlab Automation Server Type Library [XU{)l  
    3. 将名字改为MLAPP S bqM=I+

    "j@IRuH  
    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。 .Mft+,"

    现在将脚本代码公布如下,此脚本执行如下几个步骤: O |I:[S},  
    1. 创建Matlab服务器。 L4A/7Ep  
    2. 移动探测面对于前一聚焦面的位置。 ,DUQto  
    3. 在探测面追迹光线 M0IqQM57N  
    4. 在探测面计算照度 `GN5QLg#}0  
    5. 使用PutWorkspaceData发送照度数据到Matlab MKh L^c-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 CH_Dat >  
    7. 用Matlab画出照度数据 Z$=$oJzB  
    8. 在Matlab计算照度平均值 UeiJhH,u   
    9. 返回数据到FRED中 `q{'_\gVt(
