    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。 Af~$TyX  
    A7Cm5>Y_S  
    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: lV3x*4O=  
    enableservice('AutomationServer', true) $t'MSlF  
    enableservice('AutomationServer') \j}ZB<.>  
    d`=MgHz  
    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 D :4[ ~A

    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: Tt`u:ZwhF  
    1. 在FRED脚本编辑界面找到参考. ~f&E7su-6+  
    2. 找到Matlab Automation Server Type Library 1Z/(G1  
    3. 将名字改为MLAPP :(U ,x<>

    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。 >;aWz%-

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;>U2|>5V  
    1. 创建Matlab服务器。 ?8H8O %Z8  
    2. 移动探测面对于前一聚焦面的位置。 > ym,{EHK  
    3. 在探测面追迹光线 K e;E1S-~  
    4. 在探测面计算照度 U|H=Y"pL  
    5. 使用PutWorkspaceData发送照度数据到Matlab b"<liGh"n-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 TM__I\+Q  
    7. 用Matlab画出照度数据 L81ZbNU?$  
    8. 在Matlab计算照度平均值 ;RZ )  
    9. 返回数据到FRED中 58}U^IW
