    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。 ;7bY>zc(w  
    zJT,Hv .  
    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: k{ibD5B  
    enableservice('AutomationServer', true) Z$2Vd`XP  
    enableservice('AutomationServer') ^5 ~)m6=2  
    kYU!6t1  
    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 ZA8FX

    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: m_,j)A%  
    1. 在FRED脚本编辑界面找到参考. p^i]{"sjbU  
    2. 找到Matlab Automation Server Type Library O`FuXB(t  
    3. 将名字改为MLAPP i=j4Wg,{J  
    <G#z;]N

    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。 =*Y=u6?

    现在将脚本代码公布如下,此脚本执行如下几个步骤: KSy.  
    1. 创建Matlab服务器。 i*ji   
    2. 移动探测面对于前一聚焦面的位置。 8`;3`lZ  
    3. 在探测面追迹光线 A3mSSc6  
    4. 在探测面计算照度 ~.f[K{h8  
    5. 使用PutWorkspaceData发送照度数据到Matlab H\ONv=}7I  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?8aPd"x  
    7. 用Matlab画出照度数据 }*3#*y "  
    8. 在Matlab计算照度平均值 ~ZXAW~a}  
    9. 返回数据到FRED中 iMXK_O%
