    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。 a.q=  
    J3K!@m_\  
    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: wc ^z9y  
    enableservice('AutomationServer', true) *t~( _j  
        enableservice('AutomationServer') \s,ZE6dQ  
    wp} PQw:  
    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 H3&$:h  
    ,3x3&c  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: (pAGS{{  
    1. 在FRED脚本编辑界面找到参考. iLgWzA  
    2. 找到Matlab Automation Server Type Library fu33wz1$}B  
        3. 将名字改为MLAPP GUMO;rZs  
         b,s T[!X[  
         f 1]1ZOb  
    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。 >R :Bkf-

    现在将脚本代码公布如下,此脚本执行如下几个步骤: D;m>9{=  
    1. 创建Matlab服务器。 F(mm0:lT  
    2. 移动探测面对于前一聚焦面的位置。 I>:M1Yc0  
    3. 在探测面追迹光线 q*52|?  
    4. 在探测面计算照度 bKiV<&Z5d  
    5. 使用PutWorkspaceData发送照度数据到Matlab $O=m/l $  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 RH~KaV3  
    7. 用Matlab画出照度数据 S)p1[&" M  
    8. 在Matlab计算照度平均值 .I<#i9Le  
    9. 返回数据到FRED中 `Fnt#F}
