    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。 xQ?>72grP  
    A#u U ]S  
    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: w$gvgz  
    enableservice('AutomationServer', true) e r" w{  
    enableservice('AutomationServer') \lL[08G  
    y48]|%73  
    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 Nk~}aj

    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: owVvbC2<b(  
    1. 在FRED脚本编辑界面找到参考. \j)Evjw  
    2. 找到Matlab Automation Server Type Library J )1   
    3. 将名字改为MLAPP vwR_2u

    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。 _sjS'*]

    现在将脚本代码公布如下,此脚本执行如下几个步骤: DF%d/a{]  
    1. 创建Matlab服务器。 I-v} DuM  
    2. 移动探测面对于前一聚焦面的位置。  ` Xc7b  
    3. 在探测面追迹光线 VA/2$5Wu  
    4. 在探测面计算照度 5f0M{J,KC  
    5. 使用PutWorkspaceData发送照度数据到Matlab :]"5UY?oF  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4^_6~YP7  
    7. 用Matlab画出照度数据 ,CE/o7.FG  
    8. 在Matlab计算照度平均值 =4y gbk  
    9. 返回数据到FRED中 LPs%^*8(2
