    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。 fjG/dhr  
    ^&e;8d|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: <C2c" =b  
    enableservice('AutomationServer', true) 5"]aZMua  
    enableservice('AutomationServer') i@%L_[MtA  
    lK 9s0t'  
    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 /Ir 7 DZK

    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: I[vME"  
    1. 在FRED脚本编辑界面找到参考. 72% {Wh/  
    2. 找到Matlab Automation Server Type Library zh?xIpY  
    3. 将名字改为MLAPP H==X0

    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。 r{c5dQ

    1. 创建Matlab服务器。 4t"*)xy  
    2. 移动探测面对于前一聚焦面的位置。 thR|h+B  
    3. 在探测面追迹光线 "4k"U1  
    4. 在探测面计算照度 hlt9x.e.A  
    5. 使用PutWorkspaceData发送照度数据到Matlab /<G yg7o0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 K>`m_M"LA  
    7. 用Matlab画出照度数据 s$eK66H  
    8. 在Matlab计算照度平均值 ^!XU+e+:0
