    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。 ZW0gd7Wh  
    6(uK5eD(!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: -1 Ok_h"  
    enableservice('AutomationServer', true) >u:t2DxE  
    enableservice('AutomationServer') 5s'oVO*hW  
    HX77XTy  
    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 6*n<emP  
    }+fMYgw  
    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:  8~>5k  
    1. 在FRED脚本编辑界面找到参考. 5_MqpCL  
    2. 找到Matlab Automation Server Type Library L| uoFG{  
    3. 将名字改为MLAPP NY`$D}Bi

    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。 6eNo}Tos9

    现在将脚本代码公布如下,此脚本执行如下几个步骤: feH|sz`e  
    1. 创建Matlab服务器。 t<|S7EqIL  
    2. 移动探测面对于前一聚焦面的位置。 23AMrDF=N  
    3. 在探测面追迹光线 [o0Z; }fU  
    4. 在探测面计算照度 g5 J[ut  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,r-l^I3<  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 }  :@s  
    7. 用Matlab画出照度数据 5B lptC  
    8. 在Matlab计算照度平均值 DKG%z~R*  
    9. 返回数据到FRED中 Wp[R$/uT
