    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。 v9O~@v{=  
    A`o8'+`C  
    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: [!]2 djc  
    enableservice('AutomationServer', true) tr}Loq\y  
    enableservice('AutomationServer') SPmq4  
    N7 $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 2Gaa(rJ5o  
    h6`6tk  
    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: T\ >a!  
    1. 在FRED脚本编辑界面找到参考. ; _1 at  
    2. 找到Matlab Automation Server Type Library KE3;V2Ym f  
    3. 将名字改为MLAPP >{J(>B\  
    :I^;jdL  
    ):_\;.L  
    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。 <.izVD4/Gg

    现在将脚本代码公布如下,此脚本执行如下几个步骤: \WB<86+z  
    1. 创建Matlab服务器。  l(tOe  
    2. 移动探测面对于前一聚焦面的位置。 r{I% \R!@  
    3. 在探测面追迹光线 JB]q   
    4. 在探测面计算照度 $ Kncvu  
    5. 使用PutWorkspaceData发送照度数据到Matlab .I0qGg  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 0Bi.6r  
    7. 用Matlab画出照度数据 @Y<bwv  
    8. 在Matlab计算照度平均值 1--C~IjJ+  
    9. 返回数据到FRED中 >!bJslWA
