    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。 >+8Kl`2sw;  
    B9(e"cMm  
    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: \]gUX-  
    enableservice('AutomationServer', true) LYvjqNC&4  
    enableservice('AutomationServer') H% "R _[+  
    0CFON2I  
    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 7m +d;x2

    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: #k*P/I~  
    1. 在FRED脚本编辑界面找到参考. %tC3@S  
    2. 找到Matlab Automation Server Type Library xKW`m  
    3. 将名字改为MLAPP /ig'p53jL

    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。 ^g eC?m

    现在将脚本代码公布如下,此脚本执行如下几个步骤: &Y/Myh[P  
    1. 创建Matlab服务器。 ^N`bA8  
    2. 移动探测面对于前一聚焦面的位置。 ^:F |2  
    3. 在探测面追迹光线 {:m%n-  
    4. 在探测面计算照度 +#IsRiH%>  
    5. 使用PutWorkspaceData发送照度数据到Matlab qJ8@A}}8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 c 6"hk_  
    7. 用Matlab画出照度数据 @+(TM5Ub  
    8. 在Matlab计算照度平均值 d5z?QI  
    9. 返回数据到FRED中 1O{x9a5Z?O
