    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。 Lo[;{A$u  
    [r]<~$  
    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: (ux9"r^g;x  
    enableservice('AutomationServer', true) <#Fex'4  
    enableservice('AutomationServer') v7+|G'8M`  
    +N~{6*@uz,  
    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  .;vd  
    i)'u!V  
    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: b5|l8<\  
    1. 在FRED脚本编辑界面找到参考. X2~KNw  
    2. 找到Matlab Automation Server Type Library ex|)3|J  
    3. 将名字改为MLAPP +K=RMqM-8  
    3!?QQT,!)

    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。 oe9S$C;$'

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 4^6Oh#p0  
    1. 创建Matlab服务器。 s.Mrd~(Drz  
    2. 移动探测面对于前一聚焦面的位置。 3WfZzb+  
    3. 在探测面追迹光线 $Ixd;`l*  
    4. 在探测面计算照度 N0 t26| A  
    5. 使用PutWorkspaceData发送照度数据到Matlab v!mP9c j  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 N7s9"i  
    7. 用Matlab画出照度数据 l29AC}^  
    8. 在Matlab计算照度平均值 ri9n.-xs  
    9. 返回数据到FRED中 uxq#q1
