    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。 m)"wd$O^w  
    'G8.)eTA'  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: xy Pz_9  
    enableservice('AutomationServer', true) zMbz_22*  
    enableservice('AutomationServer') ;6/dFOZn  
    L0EF CQ7  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 rh$q]  
    5/C#*%EH'  
    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: `uLH3sr  
    1. 在FRED脚本编辑界面找到参考. &C6Z{.3V  
    2. 找到Matlab Automation Server Type Library :}3;z'2]l  
    3. 将名字改为MLAPP (f>~+-IL  
    m+'vrxTY  
    $i.)1.x  
    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。 zqs|~W]c

    现在将脚本代码公布如下,此脚本执行如下几个步骤: &M2SqeR62;  
    1. 创建Matlab服务器。 MrFi0G7u  
    2. 移动探测面对于前一聚焦面的位置。 ;=F]{w]$+  
    3. 在探测面追迹光线 4.qW ~ W{  
    4. 在探测面计算照度 5,u'p8}.  
    5. 使用PutWorkspaceData发送照度数据到Matlab *\T ]Z&E"  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 7^*[ XH  
    7. 用Matlab画出照度数据 XfYhLE  
    8. 在Matlab计算照度平均值 uwhb-.w  
    9. 返回数据到FRED中 /G& %T
