    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。 <FK7Rz:4T  
    {UZli[W1  
    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: E(U}$Zey  
    enableservice('AutomationServer', true) (*fsv g~  
    enableservice('AutomationServer') AQ 7e  
    c)E[K-u  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 cmN0ya  
    "x$S%:p  
    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: ?3z+|;t6C  
    1. 在FRED脚本编辑界面找到参考. <p0$Q!^dK=  
    2. 找到Matlab Automation Server Type Library N<>dg  
    3. 将名字改为MLAPP (\/HGxv  
    e#HP+b$  
    Z#o\9/{(R  
    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。 _@prv7e

    现在将脚本代码公布如下,此脚本执行如下几个步骤: '/ &"  
    1. 创建Matlab服务器。 -6tF   
    2. 移动探测面对于前一聚焦面的位置。 C${TC+z  
    3. 在探测面追迹光线 >6DY3\  
    4. 在探测面计算照度 QT&{M #Ydn  
    5. 使用PutWorkspaceData发送照度数据到Matlab ycAQPz}=I  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8rpN2M 3h  
    7. 用Matlab画出照度数据 VDmd+bvJV  
    8. 在Matlab计算照度平均值  B-gr2-  
    9. 返回数据到FRED中 S~Hj. d4/
