    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。 _97A9wHj  
    _~f&wkc  
    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: @di mZsi1  
    enableservice('AutomationServer', true) #QdBI{2  
        enableservice('AutomationServer') yyZV/ x~  
    3DH} YAUU  
    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 O)g\/uRy  
    .Y}~2n  
    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: m Cvgs  
    1. 在FRED脚本编辑界面找到参考. -nP y?>p"|  
    2. 找到Matlab Automation Server Type Library p<#WueR[  
        3. 将名字改为MLAPP %5|awWo_?  
         d(u"^NH;  
         w0n.Y-v4i  
    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。 ;c1ar)G7

    1. 创建Matlab服务器。 QkJAjmB  
    2. 移动探测面对于前一聚焦面的位置。 L F\4>(C2g  
    3. 在探测面追迹光线 - inZX`afA  
    4. 在探测面计算照度 :q_(=EA  
    5. 使用PutWorkspaceData发送照度数据到Matlab `w@8i[2J  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 %3B0s?,I  
    7. 用Matlab画出照度数据 *c<=IcA  
    8. 在Matlab计算照度平均值 :77dl/d%  
    9. 返回数据到FRED中 3 o=R_%r
