    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。 @TJ2 |_s6]  
    ~e _  
    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: H=*lj.x  
    enableservice('AutomationServer', true) dUL*~%2I  
    enableservice('AutomationServer') Vg(FF "  
    t|m=X  
    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 Dkg^B@5Xr  
    >dJ[1s]  
    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: 'Q"Mu  
    1. 在FRED脚本编辑界面找到参考. z.Vf,<H  
    2. 找到Matlab Automation Server Type Library I7HGV(  
    3. 将名字改为MLAPP EXsVZg"#

    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。 Z*n4$?%W

    现在将脚本代码公布如下,此脚本执行如下几个步骤: m.FN ttkM  
    1. 创建Matlab服务器。 j;I( w [@P  
    2. 移动探测面对于前一聚焦面的位置。 LYr9a(  
    3. 在探测面追迹光线 mV0u:ws  
    4. 在探测面计算照度 m@']%X*(,  
    5. 使用PutWorkspaceData发送照度数据到Matlab e8M0Lz#}  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 biZ=TI2P,L  
    7. 用Matlab画出照度数据 J+T tM>  
    8. 在Matlab计算照度平均值 X]D:vuB  
    9. 返回数据到FRED中 shEAr*u
