    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。 8jMw7ti  
    -iR}kP|  
    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: jdK~]eld=  
    enableservice('AutomationServer', true) 0 x4Xs  
    enableservice('AutomationServer') l"W9uS;\T  
    /$|C s  
    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 I ^?TabL

    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: eY-W5TgU  
    1. 在FRED脚本编辑界面找到参考. (Dlh;Ic r9  
    2. 找到Matlab Automation Server Type Library WJ<nc+/v:  
    3. 将名字改为MLAPP Mi%i_T^i

    fFMGpibkM  
    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。 T&oY:1D,g

    1. 创建Matlab服务器。 b^~ keQ  
    2. 移动探测面对于前一聚焦面的位置。 P(l$5x]g,  
    3. 在探测面追迹光线 ^HgQ"dD <  
    4. 在探测面计算照度 ` .|JTm[  
    5. 使用PutWorkspaceData发送照度数据到Matlab mKugb_d?  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 LBq~?Q.e  
    7. 用Matlab画出照度数据 'Ybd'|t{}  
    8. 在Matlab计算照度平均值 (dd+wx't  
    9. 返回数据到FRED中 d&BocJ
