    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。 W$X/8K bn  
    B*:I-5  
    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: w7` pbcY,  
    enableservice('AutomationServer', true) 4M%|N  
    enableservice('AutomationServer') |[~ S&  
    6Gg`ExcT5  
    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 )&E]

    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: ^zTe9:hz/\  
    1. 在FRED脚本编辑界面找到参考. r\QV%09R  
    2. 找到Matlab Automation Server Type Library iuj%.}  
    3. 将名字改为MLAPP |fyzb=Lg

    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*G(`Zl}

    2. 移动探测面对于前一聚焦面的位置。 n;Mk\*Cg  
    3. 在探测面追迹光线 5=*i!c _m  
    4. 在探测面计算照度 eV%{XR?y  
    5. 使用PutWorkspaceData发送照度数据到Matlab onmpMU7w  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 -'O|D}  
    7. 用Matlab画出照度数据 r<kgYU`  
    8. 在Matlab计算照度平均值 j|8!gW  
    9. 返回数据到FRED中 _N:$|O#
