    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。 |e; z"-3  
    k+GK1Yl  
    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: K2o0L5Lke  
    enableservice('AutomationServer', true) 3k[<4-  
    enableservice('AutomationServer') RqjDMN:  
    T0"0/{5-_  
    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 otH[?c?BT  
    M*@ aA XM  
    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: u{nWjqrM*5  
    1. 在FRED脚本编辑界面找到参考. 7 8inh%  
    2. 找到Matlab Automation Server Type Library v4a4*rBI"  
    3. 将名字改为MLAPP +P)[|y +e  
    $JSC+o(q3#  
    `iayh  
    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。 'xXqEwi4

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Y^m=_*1g5  
    1. 创建Matlab服务器。 gsm^{jB  
    2. 移动探测面对于前一聚焦面的位置。 =RE_Urt:  
    3. 在探测面追迹光线 R$&&kmJ  
    4. 在探测面计算照度 #|1QA3KzO  
    5. 使用PutWorkspaceData发送照度数据到Matlab =X5&au o  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?CZD^>6  
    7. 用Matlab画出照度数据 -R \ @W q@  
    8. 在Matlab计算照度平均值 R*{?4NKG  
    9. 返回数据到FRED中 uW'4 Kt
