    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。 af@R\"N9c  
    ,#Pp_f<  
    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: O0l1AX"  
    enableservice('AutomationServer', true) c T21  
    enableservice('AutomationServer') J]W? V vv  
    o[I s$j  
    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 &s#OiF8

    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: h ?_@nQ!  
    1. 在FRED脚本编辑界面找到参考. QXI#gA  =  
    2. 找到Matlab Automation Server Type Library  "tT68  
    3. 将名字改为MLAPP .(^%M 2:6

    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。 ]qb>O:T

    现在将脚本代码公布如下,此脚本执行如下几个步骤: $bU.6  
    1. 创建Matlab服务器。 _U|rTil  
    2. 移动探测面对于前一聚焦面的位置。 @Os0A  
    3. 在探测面追迹光线  eC[G4  
    4. 在探测面计算照度 &8;Fi2}(L  
    5. 使用PutWorkspaceData发送照度数据到Matlab `3eQ#,G!  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "M;[c9  
    7. 用Matlab画出照度数据 !_q=r[D\  
    8. 在Matlab计算照度平均值 : ]JMsa6  
    9. 返回数据到FRED中 AvVPPEryal
