    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。 {vE(l'  
    -&e92g&n   
    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: x{&w?ng  
    enableservice('AutomationServer', true) >~\89E 02  
    enableservice('AutomationServer') F]I=+T   
    o5n^!gi4  
    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;+[i  
    Z,X'-7YkU  
    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<<9y  
    1. 在FRED脚本编辑界面找到参考. SZ_V^UX_  
    2. 找到Matlab Automation Server Type Library b,IocD6v;P  
    3. 将名字改为MLAPP ~j'l.gQb  
    h},oF!,  
    8/"fWm/  
    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。 u(!&:A9JFd

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Pe2wsR"_U  
    1. 创建Matlab服务器。 Cb:gH}j  
    2. 移动探测面对于前一聚焦面的位置。 RJeSi`19T)  
    3. 在探测面追迹光线 _xLHrT!y  
    4. 在探测面计算照度 <A.W 8b7D  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5IKL#V `3a  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ="d*E/##  
    7. 用Matlab画出照度数据 Y\=FLO9  
    8. 在Matlab计算照度平均值  LZ~"VV^  
    9. 返回数据到FRED中 &J!aw
