    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。 "QV?C  
    sX,."@[  
    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: xO` `X<  
    enableservice('AutomationServer', true) UpoTXA D}k  
    enableservice('AutomationServer') c]OK)i-{l  
    @`D`u16]i  
    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 xDtJ& 6uFw  
    V\=QAN^  
    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: V=+wsc  
    1. 在FRED脚本编辑界面找到参考. v;_k*y[VV$  
    2. 找到Matlab Automation Server Type Library BT3X7Cx  
    3. 将名字改为MLAPP |PY*"Ul  
    :tTP3 t5  
     FTk`Mq  
    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。 920 o]Dh=t

    现在将脚本代码公布如下,此脚本执行如下几个步骤: q>^x ,:L  
    1. 创建Matlab服务器。 4Ww.CkRG  
    2. 移动探测面对于前一聚焦面的位置。 ndB [f  
    3. 在探测面追迹光线 FKVf_Ncf%  
    4. 在探测面计算照度 wgV?1S>Z  
    5. 使用PutWorkspaceData发送照度数据到Matlab hp< NVST  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 c c^I9g~  
    7. 用Matlab画出照度数据 >AUj4d  
    8. 在Matlab计算照度平均值 !92zC._  
    9. 返回数据到FRED中 HZ8k%X}1
