    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。 ()C^ta_]  
    X}j'L&{F@  
    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: cl8_rt  
    enableservice('AutomationServer', true) d@6:|auO  
    enableservice('AutomationServer') 2&gVZz  
    9U7Mu;4  
    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 8 5%Pq:E  
    &=z1$ih>2\  
    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: _7=pw5[  
    1. 在FRED脚本编辑界面找到参考. yxCM l.  
    2. 找到Matlab Automation Server Type Library uZ/7t(fy  
    3. 将名字改为MLAPP fmnRUN=  
    W7*_T]  
    BK(pJNBh  
    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。 A&|Wvb=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: tB,.  
    1. 创建Matlab服务器。 !$p2z_n$@.  
    2. 移动探测面对于前一聚焦面的位置。 7~kpRa@\P  
    3. 在探测面追迹光线 u+z .J4w  
    4. 在探测面计算照度 hsHVX[<5`  
    5. 使用PutWorkspaceData发送照度数据到Matlab e7XsyL'|p  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 A]Q1&qM%  
    7. 用Matlab画出照度数据 9{O2B5u1  
    8. 在Matlab计算照度平均值 8K@"B  
    9. 返回数据到FRED中 ^A *]&%(h
