    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。 W?du ]  
    a&B@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: FPu$Nd&\  
    enableservice('AutomationServer', true) X5=I{eY}  
    enableservice('AutomationServer') p,7?rI\N  
    h79~d%-  
    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 )oZ2,]us!  
    }bnodb^.7  
    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: /b410NP5  
    1. 在FRED脚本编辑界面找到参考. -f"{%<Q  
    2. 找到Matlab Automation Server Type Library 1tlqw  
    3. 将名字改为MLAPP @GF3g=  
    d1 lxz?r  
    @%r "7%tq>  
    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。 Fm+V_.H/;

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ow#8oUf=  
    1. 创建Matlab服务器。 Nr`v|_U  
    2. 移动探测面对于前一聚焦面的位置。 rnBp2'EM  
    3. 在探测面追迹光线 z</^qy  
    4. 在探测面计算照度 -:Bgp*S  
    5. 使用PutWorkspaceData发送照度数据到Matlab d"thM  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 j? Vs"d|  
    7. 用Matlab画出照度数据 P[jh^!<j  
    8. 在Matlab计算照度平均值 {HjJ9ZGQ  
    9. 返回数据到FRED中 SUD~@]N1
