    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。 ;$1x_ Cb  
    X2;72  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: "VHT5k  
    enableservice('AutomationServer', true) k h*WpX  
    enableservice('AutomationServer') 1Z;cb0:  
    Vr"'O6  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 a5O$he

    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: #`= >Mza  
    1. 在FRED脚本编辑界面找到参考. M #0v# {o  
    2. 找到Matlab Automation Server Type Library . XbDb  
    3. 将名字改为MLAPP n[qnrk*3 %  
    _3N,oCRm

    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。 OC-d5P

    现在将脚本代码公布如下,此脚本执行如下几个步骤: I![/bwObG  
    1. 创建Matlab服务器。 ^jdtp  
    2. 移动探测面对于前一聚焦面的位置。 sa/9r9hc+  
    3. 在探测面追迹光线 vN@04a\h  
    4. 在探测面计算照度 Pg`+Q^^6S  
    5. 使用PutWorkspaceData发送照度数据到Matlab c&%3k+j  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ubsv\[:C  
    7. 用Matlab画出照度数据 U HTxNK@}  
    8. 在Matlab计算照度平均值 kB5y}v.3 S  
    9. 返回数据到FRED中 z#|Auc0
