    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。 _ehU:3L`s  
    h*d,AJz &.  
    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: TC2aD&cw{  
    enableservice('AutomationServer', true) b,c vQD  
    enableservice('AutomationServer') )S%mKdOm $  
    Bq!P.%6p4  
    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 ;7hf'k  
    +z4NxR   
    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: [)*fN|Hy  
    1. 在FRED脚本编辑界面找到参考. :70oO}0m.  
    2. 找到Matlab Automation Server Type Library k @ Hu0x  
    3. 将名字改为MLAPP F :u}7t>  
    :>,d$f^tqE  
    xpV8_Gz;  
    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。 9orza<#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: lyib+Sa ?`  
    1. 创建Matlab服务器。 v7ae^iU  
    2. 移动探测面对于前一聚焦面的位置。 _ pJU~8  
    3. 在探测面追迹光线 6G( k{S  
    4. 在探测面计算照度 !PO(Bfd  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2Two|E  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 0{j>u`  
    7. 用Matlab画出照度数据 >uQ!B/C!  
    8. 在Matlab计算照度平均值 ^iGIF~J9  
    9. 返回数据到FRED中 1D*e u
