    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。 6]rrj  
    MfL q h  
    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: uWfse19  
    enableservice('AutomationServer', true) -y/?w*Cx  
    enableservice('AutomationServer') |f>y"T+1  
    Y7{|EI+@  
    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 sdO;vp^:b

    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: yRgo1ow]  
    1. 在FRED脚本编辑界面找到参考. Gf%o|kX]  
    2. 找到Matlab Automation Server Type Library sztnRX_  
    3. 将名字改为MLAPP N{q'wep

    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。 72{kig9c

    现在将脚本代码公布如下,此脚本执行如下几个步骤: }pTj8Tr  
    1. 创建Matlab服务器。 DC$ S. {n  
    2. 移动探测面对于前一聚焦面的位置。 FF_$)%YUp  
    3. 在探测面追迹光线 NF a ;  
    4. 在探测面计算照度 i#-Jl7V[a  
    5. 使用PutWorkspaceData发送照度数据到Matlab 4u(}eE f7  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 %(kq Hxc  
    7. 用Matlab画出照度数据 n >eIQaV  
    8. 在Matlab计算照度平均值 8n73MF  
    9. 返回数据到FRED中 r2<+ =INn
