    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。 SjU0X b)[  
    }j#c#''i  
    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: wQ9fPOm  
    enableservice('AutomationServer', true) `ve5>aw0_Y  
    enableservice('AutomationServer') ob=IaZ@?  
    9uY$@7qH  
    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 , @6_sl  
    /57)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: ]P(_ d'}  
    1. 在FRED脚本编辑界面找到参考. Yg")/*!H  
    2. 找到Matlab Automation Server Type Library 7ZpU -':  
    3. 将名字改为MLAPP @1 )][r-7

    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。 ,N5-(W

    I!,FxOM|$  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: Ha/-v?E  
    1. 创建Matlab服务器。 c ]&|.~2&  
    2. 移动探测面对于前一聚焦面的位置。 z4c{W~}`  
    3. 在探测面追迹光线 25`6V>\  
    4. 在探测面计算照度 09rbu\h  
    5. 使用PutWorkspaceData发送照度数据到Matlab &r !*Y&  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 u+vUv~4A6  
    7. 用Matlab画出照度数据 mmgIV&P  
    8. 在Matlab计算照度平均值 FDO$(&  
    9. 返回数据到FRED中 {3=]cLtt
