    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。 \D z? h  
    K(u pz n*a  
    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: :~"m yn,  
    enableservice('AutomationServer', true) vf.MSk?~ar  
    enableservice('AutomationServer') J{\Uw].|0  
    hizM}d-"C  
    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 Iga +8k  
    \[[xyd  
    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: Aj cKz  
    1. 在FRED脚本编辑界面找到参考. RDDA^U7y#  
    2. 找到Matlab Automation Server Type Library (N&?Z]|yr  
    3. 将名字改为MLAPP +?"F=.SZ

    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。 bv]SR_Tiq

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ?C fQwY#N  
    1. 创建Matlab服务器。 y'^U4# (  
    2. 移动探测面对于前一聚焦面的位置。 rMIX{K)'f  
    3. 在探测面追迹光线 9;{(.K  
    4. 在探测面计算照度 .gC.T`/m  
    5. 使用PutWorkspaceData发送照度数据到Matlab T_Tu>wQX  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Lwi"K8.u  
    7. 用Matlab画出照度数据 P2jh[a%  
    8. 在Matlab计算照度平均值 hq {{XQ  
    9. 返回数据到FRED中 xf;>o$oN0P
