    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。 O)|P,?  
    #hfuH=&oh  
    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: /'2O.d0}.  
    enableservice('AutomationServer', true) ^jB8Q  
    enableservice('AutomationServer') S{]7C?4`  
    uP3_FX: e  
    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 1F8 W9b^D  
    u6V/JI}g  
    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: eK_*2=;XRW  
    1. 在FRED脚本编辑界面找到参考. OI1ud/>h  
    2. 找到Matlab Automation Server Type Library Y}*\[}l:&x  
    3. 将名字改为MLAPP U6ZR->:

    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。 [S]S^ej*8

    现在将脚本代码公布如下,此脚本执行如下几个步骤: @oF$LMD  
    1. 创建Matlab服务器。 b i y4 d  
    2. 移动探测面对于前一聚焦面的位置。 =h6 sPJ  
    3. 在探测面追迹光线 >Iewx Gb>  
    4. 在探测面计算照度 N/$`:8"  
    5. 使用PutWorkspaceData发送照度数据到Matlab keW~ NM  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 L TV{{Z+  
    7. 用Matlab画出照度数据 1(Y7mM8\  
    8. 在Matlab计算照度平均值 1be %G [*  
    9. 返回数据到FRED中 v0Dq@Q1
