    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。 u|prVzm\m  
    ?pq#|PI)  
    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: ST'M<G%4E  
    enableservice('AutomationServer', true) %D|p7&  
    enableservice('AutomationServer') e= $p(  
    ?v8.3EE1\o  
    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 * S4IMfp

    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=yV8.cD  
    1. 在FRED脚本编辑界面找到参考.  hUy"XXpr  
    2. 找到Matlab Automation Server Type Library jG8W|\8  
    3. 将名字改为MLAPP )/VhkSXbG!

    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。 k=D_9_

    2. 移动探测面对于前一聚焦面的位置。 2JY]$$K7  
    3. 在探测面追迹光线 La&?0PA  
    4. 在探测面计算照度 B!:%^S  
    5. 使用PutWorkspaceData发送照度数据到Matlab 8 nCw1   
    6. 使用PutFullMatrix发送标量场数据到Matlab中 wuRB[KLe  
    7. 用Matlab画出照度数据 "9W] TG  
    8. 在Matlab计算照度平均值 iZsZSW \  
    9. 返回数据到FRED中 qPle=6U[IL
