    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。 <{cQM$ #  
    5L%'@`mX  
    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: Rtl"Ub@HV  
    enableservice('AutomationServer', true) b5vC'B-!  
    enableservice('AutomationServer') Qn.om=KDs@  
    sIGMA$EK  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 ,m:.-iy?  
    AjMh,@  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: IfAZn_  
    1. 在FRED脚本编辑界面找到参考. ,T$U'&;  
    2. 找到Matlab Automation Server Type Library d.d/<  
    3. 将名字改为MLAPP 24*XL,  
    '9J/T57]e  
    ChPmX+.i_  
    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。 l'.VKh\C

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 3$>1FoSk  
    1. 创建Matlab服务器。 q"8e a/  
    2. 移动探测面对于前一聚焦面的位置。 X *"i6 *  
    3. 在探测面追迹光线 xy[3u?,&s!  
    4. 在探测面计算照度 SsDmoEeB[  
    5. 使用PutWorkspaceData发送照度数据到Matlab Vaw+.sG`AP  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @9RM9zK.q  
    7. 用Matlab画出照度数据 6}Ci>_i4#  
    8. 在Matlab计算照度平均值 jcf7n`L  
    9. 返回数据到FRED中 ?X<eV1a
