    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。 dGt;t5An V  
    1\z5[ _  
    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: 0UB)FK ,9  
    enableservice('AutomationServer', true) luACdC  
    enableservice('AutomationServer') n2zJ'  
    &|'1.^f@;E  
    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 5D8V)i  
    Wz)s#  
    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 Y*JNx  
    1. 在FRED脚本编辑界面找到参考. Y #E/"x%+  
    2. 找到Matlab Automation Server Type Library :aI[ lZ  
    3. 将名字改为MLAPP z lco? Rt

    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。 wwE`YY

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :V*c9,>ZO  
    1. 创建Matlab服务器。 u|&"l  
    2. 移动探测面对于前一聚焦面的位置。 f]W$4f {  
    3. 在探测面追迹光线 9gVu:o 1/  
    4. 在探测面计算照度 Jte:U*2  
    5. 使用PutWorkspaceData发送照度数据到Matlab ZX[ @P?A+-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Tf(-Duxz  
    7. 用Matlab画出照度数据 ?9'Ukw` g  
    8. 在Matlab计算照度平均值 pKJ0+mN#"  
    9. 返回数据到FRED中 mlW0ptp
