    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。 ~S,,w1`  
    |3KLk?2  
    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:  cHk)i  
    enableservice('AutomationServer', true) lE(a%'36  
    enableservice('AutomationServer') pz.JWCU1  
    B e0ND2oo  
    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 M]2]\km

    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: 85Otss/mM  
    1. 在FRED脚本编辑界面找到参考. ) iN/ua  
    2. 找到Matlab Automation Server Type Library /~$WUAh  
    3. 将名字改为MLAPP ?b>,9A.Z  
    yj.7'{mA  
    '|8} z4/g  
    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。 2KYw}j|5

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ?Yth0O6?sb  
    1. 创建Matlab服务器。 (Hb:?(  
    2. 移动探测面对于前一聚焦面的位置。  jYmR  
    3. 在探测面追迹光线 NUWDc]@J*  
    4. 在探测面计算照度 3@$,s~+ 3  
    5. 使用PutWorkspaceData发送照度数据到Matlab g'n7T|h ~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 biU^[g("  
    7. 用Matlab画出照度数据 ?En O"T.  
    8. 在Matlab计算照度平均值 MS 81sN\d  
    9. 返回数据到FRED中 2Ay* kmW
