    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。 P 6La)U`VA  
    B]()  
    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: j%w^8}U>G  
    enableservice('AutomationServer', true) 5~jz| T}s  
    enableservice('AutomationServer') tK/,U =+  
    (S+/e5c)  
    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 Mlo,F1'?>  
    La '6k  
    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: 19y,O0# _  
    1. 在FRED脚本编辑界面找到参考. P2aFn=f  
    2. 找到Matlab Automation Server Type Library w $-q&  
    3. 将名字改为MLAPP G `!A#As  
    Aaq%'07ihW  
    ]d7A|)q  
    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。 } S]!W\a

    现在将脚本代码公布如下,此脚本执行如下几个步骤: !5?_)  
    1. 创建Matlab服务器。 /VufL+q1  
    2. 移动探测面对于前一聚焦面的位置。 j3`YaWw  
    3. 在探测面追迹光线 BN%cX 2j  
    4. 在探测面计算照度 +L.D3  
    5. 使用PutWorkspaceData发送照度数据到Matlab FJCORa@?_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 3c,4 wyn  
    7. 用Matlab画出照度数据 y?O-h1"3,  
    8. 在Matlab计算照度平均值 vazA@|^8  
    9. 返回数据到FRED中 ISFNP&& K
