    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。 ia6 jiW x  
    AXfU$~  
    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: ^ 5 >e  
    enableservice('AutomationServer', true) 5<?Ah+1  
    enableservice('AutomationServer') 4Z)4WGp!  
    k(Yz2  
    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 5Z=4%P*I  
    |5@Ra@0  
    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: h!"2Ux3!x  
    1. 在FRED脚本编辑界面找到参考. F<4rn  
    2. 找到Matlab Automation Server Type Library I-v} DuM  
    3. 将名字改为MLAPP  ` Xc7b  
    :XKYfc_y  
    5f0M{J,KC  
    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。 :]"5UY?oF

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Y#U.9>h  
    1. 创建Matlab服务器。 v|?@k^Ms  
    2. 移动探测面对于前一聚焦面的位置。 uLms0r\@!  
    3. 在探测面追迹光线 G  hM  
    4. 在探测面计算照度 dQX-s=XJ  
    5. 使用PutWorkspaceData发送照度数据到Matlab ^[ae )}  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ktu?-?#0,  
    7. 用Matlab画出照度数据 u#05`i:Z  
    8. 在Matlab计算照度平均值 z%&FLdXgW+  
    9. 返回数据到FRED中 ~$!,-r
