    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。 e8!5 I,I  
    xY8$I6  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: N7QK> "a  
    enableservice('AutomationServer', true) w"|L:8  
    enableservice('AutomationServer') ww3-^v  
    KVaiugQ   
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 =.U[$~3q%  
    EIAc@$4  
    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: ^4hO  
    1. 在FRED脚本编辑界面找到参考. t!X. |`h  
    2. 找到Matlab Automation Server Type Library o#gWbAG;]b  
    3. 将名字改为MLAPP %y[h5*y*  
    CL;}IBd a

    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。 Tc:)- z[o

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ) 7@ `ut  
    1. 创建Matlab服务器。 h0f;F@I  
    2. 移动探测面对于前一聚焦面的位置。 F6|]4H.3Q  
    3. 在探测面追迹光线 : /N0!&7  
    4. 在探测面计算照度 fu ,}1Mq#  
    5. 使用PutWorkspaceData发送照度数据到Matlab (@VMH !3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 `?@}>.  
    7. 用Matlab画出照度数据 (D&3G;0tK  
    8. 在Matlab计算照度平均值 P=Jo+4O  
    9. 返回数据到FRED中 n\'4
