    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。 ,(`@ZFp$  
    i]$d3J3  
    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: jSYj+k  
    enableservice('AutomationServer', true) 1|gP :t}  
        enableservice('AutomationServer') ?>o39|M_w  
    b vu` =  
    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 DR0W)K ^

    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: C}1(@$  
    1. 在FRED脚本编辑界面找到参考. N'`*#UI+  
    2. 找到Matlab Automation Server Type Library bY>o%LL-  
        3. 将名字改为MLAPP 6PMu;#  
         pb{P[-f  
         AN~1E@"  
    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。 J)fS2Ni+

    现在将脚本代码公布如下,此脚本执行如下几个步骤: X2e|[MWkp  
    1. 创建Matlab服务器。 ;c>Yr ?^  
    2. 移动探测面对于前一聚焦面的位置。 @W @L%<  
    3. 在探测面追迹光线 +bO{U C[  
    4. 在探测面计算照度 7k$8i9#  
    5. 使用PutWorkspaceData发送照度数据到Matlab '[-/X a['  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 K0E ;4r  
    7. 用Matlab画出照度数据 !X.N$0  
    8. 在Matlab计算照度平均值 #SqOJX~Q
