    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。 :PT{>r[  
    /"Vd( K2Z  
    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: Ah2 {kK  
    enableservice('AutomationServer', true) ?9\D(V  
    enableservice('AutomationServer') PMytk`<`zw  
    Xq;|l?,O  
    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 0>od1/`

    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: R&Lqaek&W  
    1. 在FRED脚本编辑界面找到参考. H'k}/<%Q  
    2. 找到Matlab Automation Server Type Library 'SXHq>#gA  
    3. 将名字改为MLAPP ef`_ n+`

    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。 ^bv^&V&IB

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 6B?jc/V.R  
    1. 创建Matlab服务器。 VM%g QOo<  
    2. 移动探测面对于前一聚焦面的位置。 INA3^p'w  
    3. 在探测面追迹光线 BH0m[9nU;  
    4. 在探测面计算照度  T01Iu  
    5. 使用PutWorkspaceData发送照度数据到Matlab -P}A26qB  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 %M iv8  
    7. 用Matlab画出照度数据 1 sHjM %  
    8. 在Matlab计算照度平均值 +*8su5:[&@  
    9. 返回数据到FRED中 ,>-jZtm
