    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。 YABi`;R]'  
    qFl|q0\ A  
    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: 7-0j8$`  
    enableservice('AutomationServer', true) oArXP\#  
    enableservice('AutomationServer') Ug384RzHN  
    q,> C^p|2b  
    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 /} h"f5  
    QKhGEW~G  
    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: 0M?zotv0#  
    1. 在FRED脚本编辑界面找到参考. T^{=cx9x9  
    2. 找到Matlab Automation Server Type Library d\zUtcJwC  
    3. 将名字改为MLAPP ZUvc|5]

    :F9Oj1lM%  
    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。 +DO<M1uE

    现在将脚本代码公布如下,此脚本执行如下几个步骤: rU(-R@["  
    1. 创建Matlab服务器。 abCxB^5VL  
    2. 移动探测面对于前一聚焦面的位置。 H7k@Br  
    3. 在探测面追迹光线 sk*vmxClY  
    4. 在探测面计算照度 A~^x*#q{4  
    5. 使用PutWorkspaceData发送照度数据到Matlab $sUn'62JlU  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ))nTd=  
    7. 用Matlab画出照度数据 ,`YIcrya:  
    8. 在Matlab计算照度平均值 @sW!g;\T  
    9. 返回数据到FRED中 bAy\Sr #/
