    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。 4BduUH  
    `\RX~ $^  
    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: |&0"N[t  
    enableservice('AutomationServer', true) `lu"yF  
    enableservice('AutomationServer') .@8m\  
    Dh!iY0Lz  
    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 c5wkzY 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: =jV%O$Fx  
    1. 在FRED脚本编辑界面找到参考. |;U}'|6  
    2. 找到Matlab Automation Server Type Library n }9Msen  
    3. 将名字改为MLAPP {l*&l2

    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。 v0hfY

    1. 创建Matlab服务器。 mSk :7ozZ  
    2. 移动探测面对于前一聚焦面的位置。 o {Xw Li  
    3. 在探测面追迹光线 ;}>g1&q  
    4. 在探测面计算照度 ?2;n=&ZM  
    5. 使用PutWorkspaceData发送照度数据到Matlab $!l2=^\3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 '4^V4i  
    7. 用Matlab画出照度数据 U$/Hp#~X  
    8. 在Matlab计算照度平均值 OnPy8mC  
    9. 返回数据到FRED中 JV?RgFy
