    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。 WzD=Ol  
    =-wF Brw  
    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: cP#vzFB0>  
    enableservice('AutomationServer', true) |q0F*\z3  
        enableservice('AutomationServer') /-%0y2"7  
    7A6Qrfw  
    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 PkM]jbLe8  
    I'6 wh+  
    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: L=g(w$H  
    1. 在FRED脚本编辑界面找到参考. Rq`B'G9|c  
    2. 找到Matlab Automation Server Type Library mhh^kwW  
        3. 将名字改为MLAPP {}gx;v)  
         %gBulvg  
         2F5*C  
    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。 lICpfcc(+

    现在将脚本代码公布如下,此脚本执行如下几个步骤: O_vCZW a3  
    1. 创建Matlab服务器。 @fz0-vT,  
    2. 移动探测面对于前一聚焦面的位置。 bhk:Szqz  
    3. 在探测面追迹光线 }Pi}? 41!  
    4. 在探测面计算照度 :pz`bFJk  
    5. 使用PutWorkspaceData发送照度数据到Matlab !*I0}I ~  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 olA 1,8  
    7. 用Matlab画出照度数据 8d|/^U.w~V  
    8. 在Matlab计算照度平均值 wE*o1.  
    9. 返回数据到FRED中 %?2:1o
