    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。 k-\RdX)E  
    2M+'9 +k~  
    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: [O(8iz v  
    enableservice('AutomationServer', true) DU-&bm  
    enableservice('AutomationServer') ]Syr{|  
    2:l8RH!Y  
    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 xA2 "i2k9  
    >~k"C,6  
    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: QWV12t$v  
    1. 在FRED脚本编辑界面找到参考. m339Y2%=  
    2. 找到Matlab Automation Server Type Library @s;qmBX4  
    3. 将名字改为MLAPP IXef}%1N?

    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。 V}kQXz"9

    现在将脚本代码公布如下,此脚本执行如下几个步骤: m|w-}s,  
    1. 创建Matlab服务器。 S( r Fa  
    2. 移动探测面对于前一聚焦面的位置。 B#K{Y$!v  
    3. 在探测面追迹光线 na1*^S`[  
    4. 在探测面计算照度 G>);8T%l  
    5. 使用PutWorkspaceData发送照度数据到Matlab K`?",G?_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &%Lps_+fJ  
    7. 用Matlab画出照度数据 '{?7\+o.x  
    8. 在Matlab计算照度平均值 3B5GsI  
    9. 返回数据到FRED中 /!mF,oR!
