    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。 X z2IAiAs'  
    9gn_\!Mp  
    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: {tu* ="d=  
    enableservice('AutomationServer', true) "%A/bv\u  
        enableservice('AutomationServer') ~Msee+ZZ :  
    =k2+VI  
    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 ]0 ouJY  
    UrH^T;#  
    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: @-qxNw  
    1. 在FRED脚本编辑界面找到参考. t<|=-  
    2. 找到Matlab Automation Server Type Library ?.v!RdM+  
        3. 将名字改为MLAPP Nq9Qsia&  
         .m;1V6  
         J^ P/2a#a  
    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。 h}q+Dw.i

    现在将脚本代码公布如下,此脚本执行如下几个步骤: V>gEF'g  
    1. 创建Matlab服务器。 f|Z3VS0x  
    2. 移动探测面对于前一聚焦面的位置。 S?OK@UEJ  
    3. 在探测面追迹光线 7T_g?!sdMh  
    4. 在探测面计算照度 MZn7gT0  
    5. 使用PutWorkspaceData发送照度数据到Matlab 'RQZU*8  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 O *H:CW  
    7. 用Matlab画出照度数据 {KeHqM}e  
    8. 在Matlab计算照度平均值 RW,ew!Z  
    9. 返回数据到FRED中 ;?=nr5;q
