    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。 zQ+t@;g1  
    /8HO7E+5  
    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: EZfa0jJD  
    enableservice('AutomationServer', true) _ 7.y4zQJ  
    enableservice('AutomationServer') O; sQPG,v  
    tP{$}cEY  
    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 *03/ :q^(  
    )fL*Ws6  
    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: PCfs6.*5Mf  
    1. 在FRED脚本编辑界面找到参考. 5z>\'a1U  
    2. 找到Matlab Automation Server Type Library I@M^Wu]wW  
    3. 将名字改为MLAPP ~B\:

    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。 9v2 ;

    现在将脚本代码公布如下,此脚本执行如下几个步骤: IW_D$pq  
    1. 创建Matlab服务器。 Rw 8o]  
    2. 移动探测面对于前一聚焦面的位置。 [0#hgGO]P  
    3. 在探测面追迹光线 h'KtG<+  
    4. 在探测面计算照度 <J`xCm K  
    5. 使用PutWorkspaceData发送照度数据到Matlab mIo7 K5z{  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 l$9,  
    7. 用Matlab画出照度数据 jtY~- @*  
    8. 在Matlab计算照度平均值 ;)a9Y?  
    9. 返回数据到FRED中 @/FX7O{n:
