    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。 @BbqYX  
    eH.~c3o  
    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: L+s3@ C;b  
    enableservice('AutomationServer', true) #l kv&.)x  
    enableservice('AutomationServer') y7ng/vqM7  
    3 o=R_%r  
    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 CAX)AN  
    IKT3T_\-I  
    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: /"w%?Ea  
    1. 在FRED脚本编辑界面找到参考. qx,>j4y w  
    2. 找到Matlab Automation Server Type Library B%P g:|  
    3. 将名字改为MLAPP {C6,h#|pg  
    kXw&*B-/  
    !zc?o?~z  
    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。 B(+J?0Dj

    1. 创建Matlab服务器。 HE>6A|rgDr  
    2. 移动探测面对于前一聚焦面的位置。 UVND1XV^f  
    3. 在探测面追迹光线 Uy  $1X  
    4. 在探测面计算照度 -:mT8'.F-  
    5. 使用PutWorkspaceData发送照度数据到Matlab WvV!F?uqZ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 s];jroW@u  
    7. 用Matlab画出照度数据 ?)x"+[2  
    8. 在Matlab计算照度平均值 ~.-o*
