    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。 3 ?F@jEQk  
    !h>$bm  
    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: R"gm]SQ/  
    enableservice('AutomationServer', true) X-#mv|3  
    enableservice('AutomationServer') HF+fk*_Q  
    sDm},=X}  
    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 Z4ov

    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: G!Oq>7  
    1. 在FRED脚本编辑界面找到参考. 8;\tP29  
    2. 找到Matlab Automation Server Type Library MZW Y  
    3. 将名字改为MLAPP "Vp: z V<S  
    b[o"Uq@8?

    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。 OXX(OCG>

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 0*IY%=i  
    1. 创建Matlab服务器。 i^cM@?  
    2. 移动探测面对于前一聚焦面的位置。 W<N QU f[=  
    3. 在探测面追迹光线 \ Q8q9|g?]  
    4. 在探测面计算照度 4i\aW:_'i  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5YG@[ic  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 C+]q  
    7. 用Matlab画出照度数据 Oj lB 0  
    8. 在Matlab计算照度平均值 .'{6u;8  
    9. 返回数据到FRED中 _ KhEwd
