    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。 \7xc*v [  
    VB8eGMo  
    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: J?Q@f  
    enableservice('AutomationServer', true) /J!hKK^k  
    enableservice('AutomationServer') }waZGJLN  
    Xf{p>-+DL  
    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 TI"Ki$jC

    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: |rhB@k  
    1. 在FRED脚本编辑界面找到参考. @V Tw>=94  
    2. 找到Matlab Automation Server Type Library k@n L(2  
    3. 将名字改为MLAPP 3w[uc~f

    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。 ,5t_}d|3C=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: }I`o%GL  
    1. 创建Matlab服务器。 AtAu$"ue  
    2. 移动探测面对于前一聚焦面的位置。 >oEFuwE  
    3. 在探测面追迹光线 /9P7;1?  
    4. 在探测面计算照度 7Ot&]M  
    5. 使用PutWorkspaceData发送照度数据到Matlab ?h#F& y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !@ AnwV]  
    7. 用Matlab画出照度数据 t0:~BYXu  
    8. 在Matlab计算照度平均值 D`B*+  
    9. 返回数据到FRED中 UA0( cK
