    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。 (ov&iNx  
    -xN/H,xok  
    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: fBz|-I:k +  
    enableservice('AutomationServer', true) Q00v(6V46  
    enableservice('AutomationServer') T (]*jaB  
    dD~H ft  
    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 /& c2y=/'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: \i}-Y[Dg  
    1. 在FRED脚本编辑界面找到参考. D@ !r?E`  
    2. 找到Matlab Automation Server Type Library gX(Xj@=(&  
    3. 将名字改为MLAPP ^Pu:&:ki  
    #T{)y

    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。 =K|#5p`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: >Bdh`Ot-!  
    1. 创建Matlab服务器。 >ke.ZZV?  
    2. 移动探测面对于前一聚焦面的位置。 ]s E)-8  
    3. 在探测面追迹光线 i: jB  
    4. 在探测面计算照度 }; M@JMu,  
    5. 使用PutWorkspaceData发送照度数据到Matlab 8t) g fSG  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 o~L(;A]yN  
    7. 用Matlab画出照度数据 `g)  
    8. 在Matlab计算照度平均值 _O11SiP]  
    9. 返回数据到FRED中 BIew\N
