    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。 T|\sN*}\8J  
    !"phz&E5ah  
    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: ,Z|O y|+'  
    enableservice('AutomationServer', true) 0*:n<T9  
    enableservice('AutomationServer') rs4:jS$)  
    fX9b1x  
    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 =4q5KI

    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: Onqapm0  
    1. 在FRED脚本编辑界面找到参考. <8%+-[(  
    2. 找到Matlab Automation Server Type Library u^C\aujg  
    3. 将名字改为MLAPP L~+aD2 E {  
    q:up8-LAr  
    8Ie0L3d-  
    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。 Y]R=z*i%

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :F5(]g 7  
    1. 创建Matlab服务器。 d<?Zaehe\  
    2. 移动探测面对于前一聚焦面的位置。 *W2] Kxx*  
    3. 在探测面追迹光线 e{2Za   
    4. 在探测面计算照度 LkeYzQH/l  
    5. 使用PutWorkspaceData发送照度数据到Matlab $igMk'%Nmb  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 im>/$!&OyI  
    7. 用Matlab画出照度数据 Wsd_RT}ww  
    8. 在Matlab计算照度平均值 &VjPdu57  
    9. 返回数据到FRED中 !K_<7iExI\
