    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<58TCd  
    c[Y7tj%y  
    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: T9(~^}_+9  
    enableservice('AutomationServer', true) TpnkJygIm  
    enableservice('AutomationServer') MEo+S  
    kKCkjA:o##  
    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 []u!piW

    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: BI}>"',  
    1. 在FRED脚本编辑界面找到参考. ) I@gy  
    2. 找到Matlab Automation Server Type Library Gd"lB*^Ht  
    3. 将名字改为MLAPP |>p\*Dl}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。 lKe aI

    现在将脚本代码公布如下,此脚本执行如下几个步骤: - 5A"TNU  
    1. 创建Matlab服务器。 RMsr7M4<91  
    2. 移动探测面对于前一聚焦面的位置。 :p OX,  
    3. 在探测面追迹光线 x!Wl&  
    4. 在探测面计算照度 F[Peil+|`  
    5. 使用PutWorkspaceData发送照度数据到Matlab &?x^I{j  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 x OZ?zN  
    7. 用Matlab画出照度数据 PN<Y&/fB  
    8. 在Matlab计算照度平均值 Mc{1Cdj  
    9. 返回数据到FRED中 ZLBfQ+pM)
