    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。 :G3PdQb^  
    nHAET  
    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: BlwAD  
    enableservice('AutomationServer', true) LqNt.d @  
    enableservice('AutomationServer') 2/XrorV  
    I5#KLZVg  
    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 o#GZ|9IL

    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: 9:DT+^BB  
    1. 在FRED脚本编辑界面找到参考. *Ubsa9'fS  
    2. 找到Matlab Automation Server Type Library  cs+;ijp  
    3. 将名字改为MLAPP * {avx  
    'e&L53n  
    Y -yozt  
    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。 {KQ-QKxxS

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Dq07Z^#'  
    1. 创建Matlab服务器。 %mqep5n(  
    2. 移动探测面对于前一聚焦面的位置。 [3K& cX}B  
    3. 在探测面追迹光线 :.DZ~I  
    4. 在探测面计算照度 _HMQx_e0YM  
    5. 使用PutWorkspaceData发送照度数据到Matlab [ TX1\*W  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 u[:-^H  
    7. 用Matlab画出照度数据 ;$nCQ/ /  
    8. 在Matlab计算照度平均值 O)N$nBnp  
    9. 返回数据到FRED中 _*l+ze[a
