    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。 E6ElNgL  
    mxC;?s;~  
    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: /nNN,hz  
    enableservice('AutomationServer', true) f}f9@>.  
    enableservice('AutomationServer') #OD/$f_  
    ?P`K7  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 7,o7Cf2z  
    i%]EEVmN  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 6SkaH<-&K  
    1. 在FRED脚本编辑界面找到参考. xF'EiX~  
    2. 找到Matlab Automation Server Type Library ,/F~ Y&1I  
    3. 将名字改为MLAPP .j0$J\:i

    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。 "$^ ~!1~

    现在将脚本代码公布如下,此脚本执行如下几个步骤: m@v\(rT.  
    1. 创建Matlab服务器。 ~KX/ Ai  
    2. 移动探测面对于前一聚焦面的位置。 xy[3u?,&s!  
    3. 在探测面追迹光线 SsDmoEeB[  
    4. 在探测面计算照度 Vaw+.sG`AP  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,f'CD{E  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @,7GaK\  
    7. 用Matlab画出照度数据 L+i=VGm0  
    8. 在Matlab计算照度平均值 k(G^z   
    9. 返回数据到FRED中 f+)L#>Gl?
