    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。 jQ\/R~)O  
    G X>T~i\f8  
    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: =J&aN1Hgt  
    enableservice('AutomationServer', true) N`i`[ f  
    enableservice('AutomationServer') H.: [# a  
    ffE>%M*  
    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 s2\6\8Ipn  
    +\`t@Ht#  
    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: 9w,u4q  
    1. 在FRED脚本编辑界面找到参考. rlVo}kc7:  
    2. 找到Matlab Automation Server Type Library o[CjRQY]P  
    3. 将名字改为MLAPP 'QEQyJ0EB  
    e.^Y4(  
    \%:]o-+"I  
    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。  al:c2o

    2. 移动探测面对于前一聚焦面的位置。 s_N]$3'[E  
    3. 在探测面追迹光线 N?;5%pG <  
    4. 在探测面计算照度 auT$-Ki8  
    5. 使用PutWorkspaceData发送照度数据到Matlab Dhe ]f#d  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #>byP?)n  
    7. 用Matlab画出照度数据 y[@<goT  
    8. 在Matlab计算照度平均值 9ApGn!`  
    9. 返回数据到FRED中 0^{?kg2o_
