    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。 EBc_RpC/Z  
    gMS-mkZ  
    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: BIqZg$  
    enableservice('AutomationServer', true)  Y[#EFM  
    enableservice('AutomationServer') ;EDc1:  
    K-vG5t0$\/  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 &NM.}f  
    5)bf$?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: >MwjUq  
    1. 在FRED脚本编辑界面找到参考. aNs~Uad1U  
    2. 找到Matlab Automation Server Type Library a\;Vly;  
    3. 将名字改为MLAPP "^Y)&<J&

    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。 bis}zv^%v

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :Yeo*v9  
    1. 创建Matlab服务器。 O|wu;1pQ  
    2. 移动探测面对于前一聚焦面的位置。 WZ,}]D  
    3. 在探测面追迹光线 #e)A  
    4. 在探测面计算照度 6:_@;/03%  
    5. 使用PutWorkspaceData发送照度数据到Matlab J8IdQ:4^l  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 >v--R8I*  
    7. 用Matlab画出照度数据 -hL0}Wy$N  
    8. 在Matlab计算照度平均值 `TwDR6&  
    9. 返回数据到FRED中 '9d<vW g
