    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。 +)qPUKb?  
    i6h:%n]Io  
    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: !Z<GUbl t  
    enableservice('AutomationServer', true) .Xg%><{~  
        enableservice('AutomationServer') ygd'Nh!@  
    XqyfeY5t  
    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 L&Qdb xn

    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: YM1tP'4j@  
    1. 在FRED脚本编辑界面找到参考. BYhPOg[  
    2. 找到Matlab Automation Server Type Library g5M-Vu  
        3. 将名字改为MLAPP o//N"S.)

    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。 0Dc$nL?TqX

    现在将脚本代码公布如下,此脚本执行如下几个步骤: q ^n6"&;*  
    1. 创建Matlab服务器。 k#5S'sCF<  
    2. 移动探测面对于前一聚焦面的位置。 8:huWjh]M  
    3. 在探测面追迹光线 qdAz3iye  
    4. 在探测面计算照度 KG4~t=J`  
    5. 使用PutWorkspaceData发送照度数据到Matlab aS'G&(_  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 vJtQ&,zG  
    7. 用Matlab画出照度数据 l!~8  
    8. 在Matlab计算照度平均值 *xkbKkm  
    9. 返回数据到FRED中 G"O %u|7
