    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。 eTp|!T  
    (s;W>,~q  
    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: AaYH(2m-  
    enableservice('AutomationServer', true) $@'BB=i  
    enableservice('AutomationServer') ?-)!dl%N  
    ({j8|{)+  
    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 5FR#CQ  
    OWewV@VXR  
    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: Qz[^J  
    1. 在FRED脚本编辑界面找到参考. MMFg{8  
    2. 找到Matlab Automation Server Type Library -SM_JR3<  
    3. 将名字改为MLAPP +XsE

    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。 yIKpyyC9H

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Bn]=T  
    1. 创建Matlab服务器。 i=#`7pt%'a  
    2. 移动探测面对于前一聚焦面的位置。 B$2b =\  
    3. 在探测面追迹光线 vT Eq T  
    4. 在探测面计算照度 D:Q#%wJ  
    5. 使用PutWorkspaceData发送照度数据到Matlab 32 i6j  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ~g=& wT11  
    7. 用Matlab画出照度数据 d/9YtG%q  
    8. 在Matlab计算照度平均值 rByth,|  
    9. 返回数据到FRED中 Z}$sY>E
