    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。 PYaOH_X.  
    ah>Dqb*  
    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: -: C[P  
    enableservice('AutomationServer', true) Fos1WH?\  
    enableservice('AutomationServer') 9c%(]Rn:  
    0O_E\- =  
    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 .C6gl]6y@

    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: 9'l.TcVm`,  
    1. 在FRED脚本编辑界面找到参考. . rRc  
    2. 找到Matlab Automation Server Type Library u>1v~3,r#  
    3. 将名字改为MLAPP aK-N}T

    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。 Of!|,2`(

    2. 移动探测面对于前一聚焦面的位置。 3EAX]  
    3. 在探测面追迹光线 :K?iNZqWN6

    5. 使用PutWorkspaceData发送照度数据到Matlab omr:C8T>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 jjNxatAN  
    7. 用Matlab画出照度数据 (]o FB$
