    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。 7$_ :sJ  
    <25ccE9^c  
    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: *#h;c1aP  
    enableservice('AutomationServer', true) ?Aw3lH#:  
    enableservice('AutomationServer') kqf8=y  
    zlkWU  
    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 j38 6gL  
    ]l&'k23~p  
    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: =4>@8=JA  
    1. 在FRED脚本编辑界面找到参考. yVYkuO  
    2. 找到Matlab Automation Server Type Library z!Hx @){|  
    3. 将名字改为MLAPP X6kaL3L}

    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。 e& Rb

    现在将脚本代码公布如下,此脚本执行如下几个步骤: aAcKwCGq\  
    1. 创建Matlab服务器。 V16%Ne  
    2. 移动探测面对于前一聚焦面的位置。 ?O7iK<5N  
    3. 在探测面追迹光线 ^ZVO ql&  
    4. 在探测面计算照度 6t$N78U  
    5. 使用PutWorkspaceData发送照度数据到Matlab (&c,twa~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 3#mE( `|P  
    7. 用Matlab画出照度数据 C P&o%Uc*  
    8. 在Matlab计算照度平均值 LG6I_[  
    9. 返回数据到FRED中 -TZ^~s
