    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。 aYL|@R5;e  
    ?!w^`D0}o  
    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: ,~ ?'Ef80  
    enableservice('AutomationServer', true) 3 <|`0pt}  
    enableservice('AutomationServer') !DjvsG1x  
    6 y"-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 NIZ<0I*5  
    M_B:{%4  
    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-RqN!snJ8  
    1. 在FRED脚本编辑界面找到参考. v/uO&iQw5  
    2. 找到Matlab Automation Server Type Library "wH)mQnd  
    3. 将名字改为MLAPP M|T4~Q U&

    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。 0uVv<Q~

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 9L%I<5i  
    1. 创建Matlab服务器。 zHB_{(o7  
    2. 移动探测面对于前一聚焦面的位置。 Y izE5[*  
    3. 在探测面追迹光线 c- $Gpa}M  
    4. 在探测面计算照度 XXmE+aI  
    5. 使用PutWorkspaceData发送照度数据到Matlab 1`f_P$&Z_J  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 si1*Wt<3Bc  
    7. 用Matlab画出照度数据 L^kp8o^$  
    8. 在Matlab计算照度平均值 `T ^G^7&  
    9. 返回数据到FRED中 &zL#hBE
