    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。 [>GblL  
    X:`=\D  
    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: X4:84  
    enableservice('AutomationServer', true) 5s^vC2$)  
    enableservice('AutomationServer') $H3C/|  
    GjW(&p$&  
    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 [-l>f P0

    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: @Yb8CB  
    1. 在FRED脚本编辑界面找到参考. WLU_t65  
    2. 找到Matlab Automation Server Type Library :,p3&2 I  
    3. 将名字改为MLAPP : ^}!"4{  
    @ ^F{

    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。 mp sX4

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 7ZAxhFC  
    1. 创建Matlab服务器。 -6_<]  
    2. 移动探测面对于前一聚焦面的位置。 /KnIU|;  
    3. 在探测面追迹光线 _G-6G=q  
    4. 在探测面计算照度 In%FOPO  
    5. 使用PutWorkspaceData发送照度数据到Matlab [?<v|k  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 3nhQ^zqf  
    7. 用Matlab画出照度数据 n=d#Fm0<  
    8. 在Matlab计算照度平均值 D8w.r"ne  
    9. 返回数据到FRED中 c{D<+XM
