    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。 ?3KI}'}EM  
    ?/#HTg)!B  
    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: ( }JX ]-  
    enableservice('AutomationServer', true) P[XE5puC  
    enableservice('AutomationServer') \FVR'A1  
    v~uwQ&AH  
    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 cY\-e?`=4

    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: /8W}o/,s5  
    1. 在FRED脚本编辑界面找到参考. _?q\tyf3  
    2. 找到Matlab Automation Server Type Library u#J5M&#  
    3. 将名字改为MLAPP n=rPFp RLF

    H7qda' %>  
    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。 Mv4JF(,S

    现在将脚本代码公布如下,此脚本执行如下几个步骤: &k1Ez  
    1. 创建Matlab服务器。 i7 p#%2  
    2. 移动探测面对于前一聚焦面的位置。 /#>?wy<s ~  
    3. 在探测面追迹光线 X*S|aNaLWW  
    4. 在探测面计算照度 mhlJzGr*q  
    5. 使用PutWorkspaceData发送照度数据到Matlab krz@1[w-j  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 b.Y[:R_9&  
    7. 用Matlab画出照度数据 'Iu$4xo`[  
    8. 在Matlab计算照度平均值 vj{h*~  
    9. 返回数据到FRED中 .6vQWt7@
