    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。 ;:8jxkx6%  
    cAsSN.HFS  
    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: YKs^%GO+  
    enableservice('AutomationServer', true) 5 ~ *'>y  
    enableservice('AutomationServer') >h/)r6  
    it/C y\f  
    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 U&d-?PI  
    kcma/d  
    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: fmZzBZ_  
    1. 在FRED脚本编辑界面找到参考. #V(Hk )  
    2. 找到Matlab Automation Server Type Library fed[^wW  
    3. 将名字改为MLAPP N~Sue  
    #C=L^cSx(  
    V fE^g\Ia  
    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。 Zo}\gg3

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 6U,U[MWJ  
    1. 创建Matlab服务器。 tswG"1R  
    2. 移动探测面对于前一聚焦面的位置。 2\iD;Z#gM  
    3. 在探测面追迹光线 Xx9~  
    4. 在探测面计算照度 EkgN6S`}  
    5. 使用PutWorkspaceData发送照度数据到Matlab Rm[rQ }:  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ,Rr&.  
    7. 用Matlab画出照度数据 b/D9P~cE  
    8. 在Matlab计算照度平均值 NZw[.s>n  
    9. 返回数据到FRED中 9cw4tqTm
