    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。 )Fw#]~Z  
    G.r =fNP  
    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:  He%v4S  
    enableservice('AutomationServer', true) <E:_9#Z0sc  
    enableservice('AutomationServer') %jJIR88  
     /i   
    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 ?4#  
    \~r_S  
    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: MwX8FYF D  
    1. 在FRED脚本编辑界面找到参考. .@\(ay  
    2. 找到Matlab Automation Server Type Library xf?"Q#  
    3. 将名字改为MLAPP .$1S-+(kV  
    qC-4X"y+

    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。 h7 mk<

    现在将脚本代码公布如下,此脚本执行如下几个步骤: s`pdy$  
    1. 创建Matlab服务器。 i6S["\h>  
    2. 移动探测面对于前一聚焦面的位置。  N!Xn)J  
    3. 在探测面追迹光线 2&=CC4<!d  
    4. 在探测面计算照度 :UX8^+bfZ  
    5. 使用PutWorkspaceData发送照度数据到Matlab wc#k@"2AZb  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 a|DCpU}  
    7. 用Matlab画出照度数据 5=fS^]- F  
    8. 在Matlab计算照度平均值 og_ylCh:  
    9. 返回数据到FRED中 Nrq/Pkmy
