    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。 %gqu7}'  
    PM:u~D$Jd  
    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: 5}9rpN{y  
    enableservice('AutomationServer', true) C?g*c  
    enableservice('AutomationServer') L?(1 [jB4G  
    }p9#Bzc  
    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 1TN+pmc}@  
    Rh@UxNy\,  
    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: ZQ\O| n8  
    1. 在FRED脚本编辑界面找到参考. ^D {v L  
    2. 找到Matlab Automation Server Type Library 7W/55ZTmJ  
    3. 将名字改为MLAPP i94)DWZ^

    ,I f9w$(z  
    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。 R|O^7o

    1. 创建Matlab服务器。 riglEA[^  
    2. 移动探测面对于前一聚焦面的位置。 I'R|B\  
    3. 在探测面追迹光线 srU*1jD)  
    4. 在探测面计算照度 ~05(92bK  
    5. 使用PutWorkspaceData发送照度数据到Matlab ~X) 1!Sr  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 fdKTj =4  
    7. 用Matlab画出照度数据 f5CnJhE|)  
    8. 在Matlab计算照度平均值 p!LaR.8]  
    9. 返回数据到FRED中 VpM(}QHd
