    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。 K:b^@>XH  
    OPJ(ub  
    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: Rh%C$d(  
    enableservice('AutomationServer', true) 'c#AGi9  
    enableservice('AutomationServer') `*y%[J,I#  
    C=x70Y/  
    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 P#-p* 4

    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: 9yWSlbPr]  
    1. 在FRED脚本编辑界面找到参考. 4P}d/w?'KL  
    2. 找到Matlab Automation Server Type Library B_S))3   
    3. 将名字改为MLAPP hQwUw foe@  
    hp$1c  
    .$a|&P=S  
    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。 9gac7(2`)

    现在将脚本代码公布如下,此脚本执行如下几个步骤: K&BaGrR  
    1. 创建Matlab服务器。 -FQc_k?VF  
    2. 移动探测面对于前一聚焦面的位置。 gf70 O>E  
    3. 在探测面追迹光线 A@jBn6  
    4. 在探测面计算照度 gUH|?@f  
    5. 使用PutWorkspaceData发送照度数据到Matlab rm4t  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 lw _@(E]E  
    7. 用Matlab画出照度数据 iz3Hoj  
    8. 在Matlab计算照度平均值  GjyTM  
    9. 返回数据到FRED中 K6s tkDhb
