    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。 :~,V+2e  
    df$pT?o  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: !nF.whq  
    enableservice('AutomationServer', true) }&EdA;/o_  
    enableservice('AutomationServer') 2]tW&y_i  
    [?)He} _L  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 :IozWPs*  
    *+J`Yk7}  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: Lcs?2c:%  
    1. 在FRED脚本编辑界面找到参考. {ka={7  
    2. 找到Matlab Automation Server Type Library 3X1 U  
    3. 将名字改为MLAPP Z$K[e

    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。 hOm0ND?;1

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 3+I"Dm,  
    1. 创建Matlab服务器。 k_ijVfI9  
    2. 移动探测面对于前一聚焦面的位置。 x0q `Uc  
    3. 在探测面追迹光线 0-Wv$o[  
    4. 在探测面计算照度 4/&.N]  
    5. 使用PutWorkspaceData发送照度数据到Matlab ?a~#`<  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Kr%O}<"  
    7. 用Matlab画出照度数据 n<>]7-
