    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。 FX{Sb"  
    % n^]1R#  
    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: Pu=YQ #F'  
    enableservice('AutomationServer', true) !>M: G:K  
    enableservice('AutomationServer') L(.5:&Y=`  
    ]]+"`t,-  
    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 7*sB"_U2

    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: ;yr 'K  
    1. 在FRED脚本编辑界面找到参考. JH 8^ZP:d'  
    2. 找到Matlab Automation Server Type Library },l3N K  
    3. 将名字改为MLAPP BwR)--75

    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。 \n}cx~j

    现在将脚本代码公布如下,此脚本执行如下几个步骤: hUqIjcuL4  
    1. 创建Matlab服务器。 )Ipa5i>t  
    2. 移动探测面对于前一聚焦面的位置。 Lx.X#n.]T  
    3. 在探测面追迹光线 L~\Ir  
    4. 在探测面计算照度 0ZO!_3m$r  
    5. 使用PutWorkspaceData发送照度数据到Matlab [l0>pHl@  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 `U(FdT  
    7. 用Matlab画出照度数据 7v{Dwg  
    8. 在Matlab计算照度平均值 qTG/7tn "  
    9. 返回数据到FRED中 Up~#]X
