    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。 RI_3X5.KQ  
    cA4xx^~  
    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: oUBn:Ir@  
    enableservice('AutomationServer', true) e[7n`ka '  
    enableservice('AutomationServer') Ol'Ct'_k,"  
    LN?W~^gsR  
    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 9IC|2w66

    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: G u-#wv5@  
    1. 在FRED脚本编辑界面找到参考. /_P5U E(  
    2. 找到Matlab Automation Server Type Library I vQ]-A}N  
    3. 将名字改为MLAPP Iw$7f kq

    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。 3R[5prE<

    现在将脚本代码公布如下,此脚本执行如下几个步骤: s^b2H !~  
    1. 创建Matlab服务器。 {? jr  
    2. 移动探测面对于前一聚焦面的位置。 M38QA  
    3. 在探测面追迹光线 x\Bl^1&  
    4. 在探测面计算照度 d[5?P?h')  
    5. 使用PutWorkspaceData发送照度数据到Matlab ^{GnEqml&  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8rXu^  
    7. 用Matlab画出照度数据 @<tkwu  
    8. 在Matlab计算照度平均值 m]$!wp  
    9. 返回数据到FRED中 . j}dk.#h
