    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。 K&gc5L  
    oe_[h]Hgl  
    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: U*+!w@ .  
    enableservice('AutomationServer', true) DGuUI}|)  
    enableservice('AutomationServer') F# 37Qv  
    m LxwJ  
    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 f!R^;'a

    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: BQfAen]  
    1. 在FRED脚本编辑界面找到参考. F+m4  
    2. 找到Matlab Automation Server Type Library uL2 {v  
    3. 将名字改为MLAPP XGup,7e9

    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。 H/la'f#o%

    2. 移动探测面对于前一聚焦面的位置。 >zx50e)  
    3. 在探测面追迹光线 [F-u'h< *l  
    4. 在探测面计算照度 G`JwAy r'  
    5. 使用PutWorkspaceData发送照度数据到Matlab eRqexqO!  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 uB&I56  
    7. 用Matlab画出照度数据 ZzaW@6LJF  
    8. 在Matlab计算照度平均值 {4jSj0W  
    9. 返回数据到FRED中 .$s|T
