    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。 la<.B^  
    QTBc_Z  
    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: g;=VuQuP|  
    enableservice('AutomationServer', true) ic`BDkNO  
    enableservice('AutomationServer') %W9R08`  
    )qb'tZz/g_  
    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 Ik^^8@z  
    .Pj<Pe  
    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: <[\I`kzq  
    1. 在FRED脚本编辑界面找到参考. h#Z[ "BG  
    2. 找到Matlab Automation Server Type Library aC`>~uX##V  
    3. 将名字改为MLAPP VIdKe&,  
    i[9yu-  
    jUM'f24  
    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。 ;>mM9^Jaf

    现在将脚本代码公布如下,此脚本执行如下几个步骤: i<F7/p "-  
    1. 创建Matlab服务器。 s1Acl\l-uF  
    2. 移动探测面对于前一聚焦面的位置。 Fn .J tIu  
    3. 在探测面追迹光线 vY_[@y  
    4. 在探测面计算照度 h_?`ESI~  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;ZUj2WxE  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 s>o#Ob@4'  
    7. 用Matlab画出照度数据 SbGdcCB  
    8. 在Matlab计算照度平均值  7qy PI  
    9. 返回数据到FRED中 )>{ .t=#
