    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。 .ox8*OO<  
    ||;hci O  
    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: @>p<3_Y1  
    enableservice('AutomationServer', true) ](&{:>RNJ  
        enableservice('AutomationServer') :.$3vaZ@  
    s;3={e.  
    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 ly:q6i  
    F;+|sMrq  
    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: ~S8*t~  
    1. 在FRED脚本编辑界面找到参考. tD+9kf2  
    2. 找到Matlab Automation Server Type Library ]=>F.GE  
        3. 将名字改为MLAPP 1IZ3=6  
         1`a5C.v  
         ~zJ?H<>  
    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。 22.8PO0

    1. 创建Matlab服务器。 vvKEv/pN7  
    2. 移动探测面对于前一聚焦面的位置。 8C67{^`::  
    3. 在探测面追迹光线 "x3lQ  
    4. 在探测面计算照度 {= F /C,-  
    5. 使用PutWorkspaceData发送照度数据到Matlab c.>oe*+  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 X)7x<?DAy  
    7. 用Matlab画出照度数据 'H \9:7  
    8. 在Matlab计算照度平均值 @te!Jgu{
