    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。 ;M\Cw.%![  
    TD4 n%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: 1Oak8 \G  
    enableservice('AutomationServer', true) w]V684[>  
    enableservice('AutomationServer') dP]Z:  
    zN-Y=-c  
    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 ?`6Mfpvj96  
    Vf=,@7  
    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: 7_lgo6  
    1. 在FRED脚本编辑界面找到参考. |t;Ktl  
    2. 找到Matlab Automation Server Type Library X?/32~\  
    3. 将名字改为MLAPP b !nA.`T  
    D}-HWJQA3  
    #Pg?T%('`  
    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|W#VyM-

    现在将脚本代码公布如下,此脚本执行如下几个步骤: A.r.tf}:  
    1. 创建Matlab服务器。 M*~XpT3  
    2. 移动探测面对于前一聚焦面的位置。 Y$+v "  
    3. 在探测面追迹光线 wOrj-Smx  
    4. 在探测面计算照度 fWDTP|DV  
    5. 使用PutWorkspaceData发送照度数据到Matlab ft iAty0n  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 <7/7+_y  
    7. 用Matlab画出照度数据 U<'z, Px6  
    8. 在Matlab计算照度平均值 &b2@+/ F  
    9. 返回数据到FRED中 GSH,;cY
