    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。 lnUy ? 0(  
    Kxn=iv^Ir  
    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: }qg&2M%\  
    enableservice('AutomationServer', true) P nDZi  
    enableservice('AutomationServer') +ZO*~.zZ  
    sa])^mkq(  
    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 ,'}ZcN2)

    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: TY}?>t+  
    1. 在FRED脚本编辑界面找到参考. CJ>=odK[  
    2. 找到Matlab Automation Server Type Library %8/$CR  
    3. 将名字改为MLAPP 9:WKG'E8a

    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。 _4w%U[GT,

    现在将脚本代码公布如下,此脚本执行如下几个步骤: -_dgd:or  
    1. 创建Matlab服务器。 78"W ~`8  
    2. 移动探测面对于前一聚焦面的位置。 70Am]L&M  
    3. 在探测面追迹光线 pD9c%P  
    4. 在探测面计算照度 nK[$ID  
    5. 使用PutWorkspaceData发送照度数据到Matlab Y;WrfO$J  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 uBXI*51{  
    7. 用Matlab画出照度数据 wKN9HT  
    8. 在Matlab计算照度平均值 1vr/|RWW  
    9. 返回数据到FRED中 A{k@V!A%
