    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。 n k@e#  
    E>2~cC*  
    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: =U)e_q  
    enableservice('AutomationServer', true) %g+*.8;"b  
    enableservice('AutomationServer') F `cuV  
    e/* T,ZJ  
    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 :^H#i:4  
    +D&aE$<  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: )e6)~3[^  
    1. 在FRED脚本编辑界面找到参考. NKJ+DD:'  
    2. 找到Matlab Automation Server Type Library 6OOdVS3\J  
    3. 将名字改为MLAPP //W7$DYEG

    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。 fO'"UI

    现在将脚本代码公布如下,此脚本执行如下几个步骤: [n!5!/g>j  
    1. 创建Matlab服务器。 !\RBOdw C  
    2. 移动探测面对于前一聚焦面的位置。 z&x3":@u<  
    3. 在探测面追迹光线 3|qT.QR`Z  
    4. 在探测面计算照度 &Bfgvws;

    6. 使用PutFullMatrix发送标量场数据到Matlab中 8kA2.pIk  
    7. 用Matlab画出照度数据 {~u#.(
