    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。 G&@d J &B  
    ,i Y:#E  
    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: !v(^wqna\  
    enableservice('AutomationServer', true) |>[qC O  
    enableservice('AutomationServer') #C~ </R%  
    a 9{:ot8,  
    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 8};kNW^2m  
    8a&c=9  
    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:  wlsx|  
    1. 在FRED脚本编辑界面找到参考. seRf q&  
    2. 找到Matlab Automation Server Type Library ' Ttsscv  
    3. 将名字改为MLAPP n#}~/\P6  
    ~( 0bqt3c  
    l($ 8H AJ  
    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。 Srz8sm;

    现在将脚本代码公布如下,此脚本执行如下几个步骤: -FI)o`AE  
    1. 创建Matlab服务器。 y:^o ._  
    2. 移动探测面对于前一聚焦面的位置。 r>7 +&s*yk  
    3. 在探测面追迹光线 %l14K_  
    4. 在探测面计算照度 #oFyi @U  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,Q3OQ[Nmh  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 G;iH.rCH  
    7. 用Matlab画出照度数据 0[M2LF!m  
    8. 在Matlab计算照度平均值 .@%L8_sMR  
    9. 返回数据到FRED中 MmfBFt*
