    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。 X8 qIia  
    B?(4f2yE  
    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: {\We72!  
    enableservice('AutomationServer', true) YOw?'+8  
    enableservice('AutomationServer') mTjm92  
    GXeAe}T  
    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 7*'@qjTos

    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: YX;nMyD?~  
    1. 在FRED脚本编辑界面找到参考. qX@9N=g`#O  
    2. 找到Matlab Automation Server Type Library qY}Cg0[@g  
    3. 将名字改为MLAPP Ar`\ N1a

    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。 9.-47|-9C

    现在将脚本代码公布如下,此脚本执行如下几个步骤: \^s2W:c  
    1. 创建Matlab服务器。 5mIXyg 0:  
    2. 移动探测面对于前一聚焦面的位置。 *H*\gaSh  
    3. 在探测面追迹光线 }} #be  
    4. 在探测面计算照度 A^vvST%7  
    5. 使用PutWorkspaceData发送照度数据到Matlab "aA_(Ydzj  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 AA.Ys89V  
    7. 用Matlab画出照度数据 &CO| Y(+  
    8. 在Matlab计算照度平均值 \CwtX(6.  
    9. 返回数据到FRED中 *o 2#eI
