    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。 mhp&; Q9  
    cJEO wAN  
    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: (S :+#v  
    enableservice('AutomationServer', true) 5K1WfdBX7)  
    enableservice('AutomationServer') +O< 0q"E  
    ];bl;BP  
    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 ^y.e Fz  
    btq`[gAF\  
    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: #!Iez vWf  
    1. 在FRED脚本编辑界面找到参考. n@LR?  
    2. 找到Matlab Automation Server Type Library  `O-LM e  
    3. 将名字改为MLAPP E"ju<q/Q

    O[p;IG`  
    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。 G)(\!0pNZ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: u-W6 hZ$  
    1. 创建Matlab服务器。 ,`7;S,f  
    2. 移动探测面对于前一聚焦面的位置。 Onr#p4UT  
    3. 在探测面追迹光线 S~"1q 0  
    4. 在探测面计算照度 M@a?j<7P,m  
    5. 使用PutWorkspaceData发送照度数据到Matlab {VC4rA  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Q AJX7  
    7. 用Matlab画出照度数据 >wK ^W{  
    8. 在Matlab计算照度平均值 c65_E<5Z  
    9. 返回数据到FRED中 lVywc:X
