    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。 b?k6-r$j  
    TbgIr  
    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: @s|yH"  
    enableservice('AutomationServer', true) [FeN(8hGS  
    enableservice('AutomationServer') [@/s! i @  
    Yduj3Ht:w  
    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 S0?e/VWy  
    &<t`EI];)4  
    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: ~9c jc  
    1. 在FRED脚本编辑界面找到参考. |N:kf&]b  
    2. 找到Matlab Automation Server Type Library C;oO=R3r  
    3. 将名字改为MLAPP #2;8/"v  
    {0 L)B{|  
    .J \i!  
    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。 ]*<!|;q

    现在将脚本代码公布如下,此脚本执行如下几个步骤: T2 /u7<D-  
    1. 创建Matlab服务器。 \omfWWpK  
    2. 移动探测面对于前一聚焦面的位置。 <=@6UPsn2  
    3. 在探测面追迹光线 %S<))G  
    4. 在探测面计算照度 1aoKf F(  
    5. 使用PutWorkspaceData发送照度数据到Matlab "B*UZ.cC  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 yD Avl+  
    7. 用Matlab画出照度数据 $LOf2kn  
    8. 在Matlab计算照度平均值 dm"|\7  
    9. 返回数据到FRED中 ~{q; - &
