    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。 n_?tN\M  
    MUnEuhXTr  
    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: QnQOm ""  
    enableservice('AutomationServer', true) I,yC D7l_  
    enableservice('AutomationServer') #Tw@wfaq)  
    F$BbYf2i  
    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 i|`dWOVb

    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: d?wc*N3  
    1. 在FRED脚本编辑界面找到参考. +M' H0-[  
    2. 找到Matlab Automation Server Type Library 5"XC$?I<}  
    3. 将名字改为MLAPP FMA6_fju4

    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。 %yBB?cp+_

    1. 创建Matlab服务器。 KlRr8 G!Z  
    2. 移动探测面对于前一聚焦面的位置。 *g?Po+ef%  
    3. 在探测面追迹光线 wE+${B03  
    4. 在探测面计算照度 wLK07e(  
    5. 使用PutWorkspaceData发送照度数据到Matlab (aOv#Vor]%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !?c|XdjZ  
    7. 用Matlab画出照度数据 8J$|NYv_b  
    8. 在Matlab计算照度平均值 1`ayc|9BR
