    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。 kk5i{.?[  
    vDOeBw=  
    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: |V~P6o(/  
    enableservice('AutomationServer', true) &FvNz  
    enableservice('AutomationServer') 8QZk0O  
    E.% F/mM  
    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 +Vf|YLbhJ  
    =v5(*$"pd"  
    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: $v oyXi`*  
    1. 在FRED脚本编辑界面找到参考. s9GPDfZ  
    2. 找到Matlab Automation Server Type Library !`#9#T|  
    3. 将名字改为MLAPP i+cGw  
    gZ!(&u  
    UZX)1?U  
    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。 ;<X3AhF

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ?H c A&  
    1. 创建Matlab服务器。 )L hO}zQ  
    2. 移动探测面对于前一聚焦面的位置。 &% r#eB?7  
    3. 在探测面追迹光线 o5$K^2^g  
    4. 在探测面计算照度 *wF:Q;_<z  
    5. 使用PutWorkspaceData发送照度数据到Matlab A07 P$3>/W  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 2nie I*[  
    7. 用Matlab画出照度数据 mVL,J=2  
    8. 在Matlab计算照度平均值 YXg uw7%\  
    9. 返回数据到FRED中 \+~4t
