    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。 FBYA d@="2  
    YJlpP0;++  
    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: ?=%Q$|]-  
    enableservice('AutomationServer', true) Z2]ySyt]  
    enableservice('AutomationServer') \B'rWk 33,  
    s.E}xv  
    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 HrUQ X4

    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: F]hKi`@  
    1. 在FRED脚本编辑界面找到参考. g9fS|T  
    2. 找到Matlab Automation Server Type Library ?t&sT  
    3. 将名字改为MLAPP (Z YGfX

    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。 &VIX?UngE

    1. 创建Matlab服务器。 o5(p&:1M  
    2. 移动探测面对于前一聚焦面的位置。 w7H.&7rF  
    3. 在探测面追迹光线 *[Ld\lRj  
    4. 在探测面计算照度 NzmVQ-4  
    5. 使用PutWorkspaceData发送照度数据到Matlab nwk66o:|  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 y`?{ 2#1H  
    7. 用Matlab画出照度数据 Hnv{sND[  
    8. 在Matlab计算照度平均值 18|i{fE;
