    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。 MLVB^<qkeH  
    m7]hJ,0  
    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: @ CsV]97`  
    enableservice('AutomationServer', true) V-O(U*]  
    enableservice('AutomationServer') VkmRh,T  
    g;p)n  
    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 |lQ;ALH!  
    'w/qcD-  
    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: "u^EleE!  
    1. 在FRED脚本编辑界面找到参考. yOXO)u1n  
    2. 找到Matlab Automation Server Type Library C"<s/h  
    3. 将名字改为MLAPP Gy29MUF

    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。 (-yl|NFBw

    现在将脚本代码公布如下,此脚本执行如下几个步骤: #XIc "L)c  
    1. 创建Matlab服务器。 O_,O,1  
    2. 移动探测面对于前一聚焦面的位置。 5fjd{Y[k  
    3. 在探测面追迹光线 +=@^i'  
    4. 在探测面计算照度 .QWhK|(.!  
    5. 使用PutWorkspaceData发送照度数据到Matlab j.?:Gaab?#  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 c=p=-j=.J  
    7. 用Matlab画出照度数据 Rs;15@t@  
    8. 在Matlab计算照度平均值 D9ufoa&ua  
    9. 返回数据到FRED中 u</8w&!
