    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。 R^n@.^8s  
    g%a|q~)  
    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: S1J<9xqSQ8  
    enableservice('AutomationServer', true) B=X,7  
    enableservice('AutomationServer') zl%>`k!>  
    3s*(uS(  
    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 syPWs57pH  
    yGj.)$1},@  
    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: iY0>lDFm.  
    1. 在FRED脚本编辑界面找到参考. DCQ^fZ/  
    2. 找到Matlab Automation Server Type Library qAY%nA>jO  
    3. 将名字改为MLAPP vq!uD!lr

    "D][e'  
    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。 &dR=?bz-A

    现在将脚本代码公布如下,此脚本执行如下几个步骤: {9LWUCpsf  
    1. 创建Matlab服务器。 jS<_ )  
    2. 移动探测面对于前一聚焦面的位置。 'ZP)cI:+X  
    3. 在探测面追迹光线 ;V5yXNQ   
    4. 在探测面计算照度 Vj?DA5W`'  
    5. 使用PutWorkspaceData发送照度数据到Matlab r0]4=6U  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 |=dC )Azs  
    7. 用Matlab画出照度数据 -JT/ 9IQ  
    8. 在Matlab计算照度平均值 nFRsc'VT  
    9. 返回数据到FRED中 o0It82?RN
