    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。 r/=v;4.W  
    %j=dKd>  
    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: $K^"a  
    enableservice('AutomationServer', true) 6gwjrGje\  
    enableservice('AutomationServer') BZEY^G  
    @PuJre4!;L  
    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 RL |.y~  
    v=nq P{  
    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: |J2_2a/"  
    1. 在FRED脚本编辑界面找到参考. !>b>"\b  
    2. 找到Matlab Automation Server Type Library w[\*\'Vm0  
    3. 将名字改为MLAPP  'vj45b

    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。 L q8}z-?

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 7{f&L '  
    1. 创建Matlab服务器。 1g9Q vz3  
    2. 移动探测面对于前一聚焦面的位置。 Je2o('MA  
    3. 在探测面追迹光线 !y$H r[v  
    4. 在探测面计算照度 ;YNN)P%"  
    5. 使用PutWorkspaceData发送照度数据到Matlab 0!veLXeK!  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 LtbL[z>]  
    7. 用Matlab画出照度数据 ZgF-.(GV  
    8. 在Matlab计算照度平均值 4>>{}c!nf  
    9. 返回数据到FRED中 WK0?$[|=r
