    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。 #P9~}JB3,  
    yWc$>ne[L  
    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: >h9I M$2  
    enableservice('AutomationServer', true) s]0{a.Cpv  
    enableservice('AutomationServer') oSKXt}sh  
    _yx>TE2e  
    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 $99n&t$Y

    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: R%WCH?B<}  
    1. 在FRED脚本编辑界面找到参考. 3pROf#M  
    2. 找到Matlab Automation Server Type Library &m7]v,&  
    3. 将名字改为MLAPP 3ZPWze6

    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。 Pj^{|U21

    现在将脚本代码公布如下,此脚本执行如下几个步骤: !-x$L>1$  
    1. 创建Matlab服务器。 RLXL&  
    2. 移动探测面对于前一聚焦面的位置。 4Z=_,#h4.  
    3. 在探测面追迹光线 tY<4%~%X  
    4. 在探测面计算照度 >>)b'c  
    5. 使用PutWorkspaceData发送照度数据到Matlab NNR`!Pty  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 .VJMz4$]O  
    7. 用Matlab画出照度数据 8'[7 )I=  
    8. 在Matlab计算照度平均值 {]!mrAjD  
    9. 返回数据到FRED中 L#{S!P,"
