    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。 d h#4/Wa,  
    \$n?J(N  
    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: a;jXMR  
    enableservice('AutomationServer', true) U?P5 cN  
    enableservice('AutomationServer') ![YLY&}s  
    6Lk<VpAa  
    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 X YO09#>&

    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: =(Y 1y$  
    1. 在FRED脚本编辑界面找到参考. gs wp:82e2  
    2. 找到Matlab Automation Server Type Library !*_5 B'  
    3. 将名字改为MLAPP .]}kOw:(#

    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。 0hnTHlk

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ]y= ff6Q  
    1. 创建Matlab服务器。 PYX]ld.E  
    2. 移动探测面对于前一聚焦面的位置。 c |OIUc  
    3. 在探测面追迹光线 O*^=  
    4. 在探测面计算照度 x;ym_UZ6e  
    5. 使用PutWorkspaceData发送照度数据到Matlab {Bk9]:'$5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *F| j%]k~  
    7. 用Matlab画出照度数据 lX$6U| !  
    8. 在Matlab计算照度平均值 ICwhqH&  
    9. 返回数据到FRED中 `oQ)qa_
