    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。 GGnlkp& E  
    HMC-^4\%[  
    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: ,jEc4ih4  
    enableservice('AutomationServer', true) }toe'6  
    enableservice('AutomationServer') d)S`.Q  
    &8w# 4*W  
    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 gyMHC{l/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: u7^(?"x  
    1. 在FRED脚本编辑界面找到参考. ~|9VVeE  
    2. 找到Matlab Automation Server Type Library I 1n,c d[  
    3. 将名字改为MLAPP V y$*v

    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。 iMt3h8

    1. 创建Matlab服务器。 g0bYO!gC r  
    2. 移动探测面对于前一聚焦面的位置。 =/_uk{  
    3. 在探测面追迹光线 5wmd[YL

    5. 使用PutWorkspaceData发送照度数据到Matlab Gc"hU:m  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 u -P !2vT  
    7. 用Matlab画出照度数据 |4g0@}nr+W  
    8. 在Matlab计算照度平均值 (5 @H
