    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。 S3sxK:  
    ~#|Pe1Y  
    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: HG&rE3@  
    enableservice('AutomationServer', true) UgD&tD0fp  
    enableservice('AutomationServer') u .,l_D_  
    c}mWAZ=wF  
    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 6$ ag<  
    )BmO[AiOM  
    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: jbTsrj"g  
    1. 在FRED脚本编辑界面找到参考. ^ ^k]2oG  
    2. 找到Matlab Automation Server Type Library &5Huv?^a'  
    3. 将名字改为MLAPP ,rWej;CzN  
    v|wO qS  
    cc:,,T /i  
    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。 @WICAC=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: /yFs$t >9  
    1. 创建Matlab服务器。 2-_d~~O1N  
    2. 移动探测面对于前一聚焦面的位置。 m[D]4h9  
    3. 在探测面追迹光线 hi^t zpy  
    4. 在探测面计算照度  @"L*!  
    5. 使用PutWorkspaceData发送照度数据到Matlab O_^t u?x  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ~ }?*v}  
    7. 用Matlab画出照度数据 &nfGRb  
    8. 在Matlab计算照度平均值 4{rj 4P?  
    9. 返回数据到FRED中 |%12Vr]J
