    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。 yXppu[=  
    6rt.ec(  
    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: 5U3="L  
    enableservice('AutomationServer', true) q' 3=  
    enableservice('AutomationServer') 0D|^S<z6  
    n|SsV  
    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 $62ospR^Y  
    e0j*e7$  
    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: S=krF yFw  
    1. 在FRED脚本编辑界面找到参考. L;fhJ~ r  
    2. 找到Matlab Automation Server Type Library 6;I&{9  
    3. 将名字改为MLAPP +To{Tm-  
    kIrME:  
    m,Q<4'  
    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。 R7ZxS

    现在将脚本代码公布如下,此脚本执行如下几个步骤: @]Iku6d-  
    1. 创建Matlab服务器。 {\;CGoN|  
    2. 移动探测面对于前一聚焦面的位置。 V_Wv(G0-\  
    3. 在探测面追迹光线 IA$:r@QNx8  
    4. 在探测面计算照度 R\A5f\L9  
    5. 使用PutWorkspaceData发送照度数据到Matlab wcsUb 9(  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ="d}:Jl  
    7. 用Matlab画出照度数据 1W$@ V!  
    8. 在Matlab计算照度平均值 -zN*2T  
    9. 返回数据到FRED中 I Zi1N
