    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。 eMsd37J  
    oc`H}Wvn  
    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: Otuf] B^s  
    enableservice('AutomationServer', true) pnOAs&QAm  
    enableservice('AutomationServer') da(<K}  
    R 9\*#c  
    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 `;C  V=,M  
    D,feF9  
    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: 7:1Lol-V  
    1. 在FRED脚本编辑界面找到参考. *] X'( /b_  
    2. 找到Matlab Automation Server Type Library &QgR*,5eo  
    3. 将名字改为MLAPP i/4>2y9/F4

    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。 i_%_x*

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 4hj|cCrO  
    1. 创建Matlab服务器。 4r}51 N\  
    2. 移动探测面对于前一聚焦面的位置。 WsB?C&>x  
    3. 在探测面追迹光线 0=YI@@n)  
    4. 在探测面计算照度 XL ^GZ  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2+XA X:YD  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "y}5;9#,  
    7. 用Matlab画出照度数据 Dd|VMW=  
    8. 在Matlab计算照度平均值 9* M,R,y  
    9. 返回数据到FRED中 z{QqY.Gu{G
