    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。 |4z IfAO  
    w<3#1/g!2B  
    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: ~?Pw& K2  
    enableservice('AutomationServer', true) $dC?Tl|B0  
    enableservice('AutomationServer') 9};8?mucr  
    qkY:3Ozw  
    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 70nqD>M4

    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: 0<@KG8@hI;  
    1. 在FRED脚本编辑界面找到参考. ~<5!?6Yt  
    2. 找到Matlab Automation Server Type Library yYYSeH  
    3. 将名字改为MLAPP ncdKj}

    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。 pRpBhm;iJ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: zxl@(h d  
    1. 创建Matlab服务器。 Y =I'czg  
    2. 移动探测面对于前一聚焦面的位置。 2\{M:\2o  
    3. 在探测面追迹光线 uyWunpT  
    4. 在探测面计算照度 Pn1^NUMZJ  
    5. 使用PutWorkspaceData发送照度数据到Matlab _8J.fT$${  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ((;!<5-`s  
    7. 用Matlab画出照度数据 -f^tE,-  
    8. 在Matlab计算照度平均值 q~o<*W   
    9. 返回数据到FRED中 $( kF#
