    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。 7S$Am84%  
    Fb=(FQ2Y?  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: 4k/B=%l  
    enableservice('AutomationServer', true) eJA$J=^R;  
    enableservice('AutomationServer') {Q],rv|;  
    ^Pl(V@  
    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 3/c3e{,!  
    C'&)""3d  
    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: ly"Jl8/<  
    1. 在FRED脚本编辑界面找到参考. aX`"V/  
    2. 找到Matlab Automation Server Type Library ^hq+ L^$^  
    3. 将名字改为MLAPP >KHR;W03

    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。 $/;D8P5/&=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: z~&uLu  
    1. 创建Matlab服务器。 uQh dg4  
    2. 移动探测面对于前一聚焦面的位置。 Z(DCR/U=(>  
    3. 在探测面追迹光线 d 90  
    4. 在探测面计算照度 6. N?=R  
    5. 使用PutWorkspaceData发送照度数据到Matlab e ewhT ^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 '%Og9Bgd+  
    7. 用Matlab画出照度数据 e R Y2.!  
    8. 在Matlab计算照度平均值 _8t5rF  
    9. 返回数据到FRED中 9U[Gh97Sf
