    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。 {4_s:+v0  
    a (U52dO,  
    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: 3.W[]zH/u  
    enableservice('AutomationServer', true) !}Xoqamm  
    enableservice('AutomationServer') u\LNJo| B  
    pRQ7rT',v  
    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 fHiL%]z  
    sL@\,]Y  
    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:  3IxC@QR  
    1. 在FRED脚本编辑界面找到参考. \,S |>CPQ  
    2. 找到Matlab Automation Server Type Library ~n=DI/AJ@-  
    3. 将名字改为MLAPP a1pp=3Pd?~

    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\*6 >

    1. 创建Matlab服务器。 X>I3N?5  
    2. 移动探测面对于前一聚焦面的位置。 l uP;P&  
    3. 在探测面追迹光线 'T eH(?3G  
    4. 在探测面计算照度 py;p7y!gxA  
    5. 使用PutWorkspaceData发送照度数据到Matlab Gz&}OO  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 2^[dy>[y0  
    7. 用Matlab画出照度数据 YR'F]FI  
    8. 在Matlab计算照度平均值 |_?e.}K
