    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。 D?Mj<||  
    ccdP}|9e  
    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: M_OvIU(E  
    enableservice('AutomationServer', true) 1 +0-VRl  
    enableservice('AutomationServer') ep$C nBwE  
    mm l`,t8  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 FQ3{~05T  
    )F$<-0pT  
    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: yx@%x?B  
    1. 在FRED脚本编辑界面找到参考. 2`[iTBZ=^  
    2. 找到Matlab Automation Server Type Library MMQ^&!H  
    3. 将名字改为MLAPP xA&RMu&  
    e #5LBSP  
    j_ \?ampF  
    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。 zc`gm~@

    现在将脚本代码公布如下,此脚本执行如下几个步骤: (/^s?`1{N?  
    1. 创建Matlab服务器。 `hVi!Q]*P  
    2. 移动探测面对于前一聚焦面的位置。 ]RvFn~E!s  
    3. 在探测面追迹光线 mr 6~8 I  
    4. 在探测面计算照度 ~OE1Sd:2  
    5. 使用PutWorkspaceData发送照度数据到Matlab S.I3m-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 -PG81F&K  
    7. 用Matlab画出照度数据 vOIzfwYG9  
    8. 在Matlab计算照度平均值 |*T`3@R;3  
    9. 返回数据到FRED中 _oILZ,
