    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。 3&y-xZu]  
    _f^6F<!  
    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: :IZAdlz[@  
    enableservice('AutomationServer', true) <L]Gk]k_R  
    enableservice('AutomationServer') D&):2F^9.  
    N0p6xg~  
    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 p}QDX*/sSu  
    r-y;"h'  
    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: ]VjvG};  
    1. 在FRED脚本编辑界面找到参考. 5mZ2CDV  
    2. 找到Matlab Automation Server Type Library dL$ iTSfz"  
    3. 将名字改为MLAPP G!Brt&_'

    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。 Tdcc<T

    现在将脚本代码公布如下,此脚本执行如下几个步骤: #NFB=o JI  
    1. 创建Matlab服务器。 4gen,^Ij  
    2. 移动探测面对于前一聚焦面的位置。 ~]-n%J $q  
    3. 在探测面追迹光线 \ivxi<SR  
    4. 在探测面计算照度 ;M.Q=#;E  
    5. 使用PutWorkspaceData发送照度数据到Matlab v Z9OJrF  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 zcP=+Y)YA  
    7. 用Matlab画出照度数据 IB;yL/T  
    8. 在Matlab计算照度平均值 .Exvuo`F  
    9. 返回数据到FRED中 gO8d2?Oh
