FRED案例-FRED如何调用Matlab

34Q;& z\e  
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。 7;cb^fi/  
|e+8Xz1>  
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: R@lmX%Z1  
enableservice('AutomationServer', true) (Uo:WyVj|F  
    enableservice('AutomationServer') z#qlu=  
hh\\api  
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。 H>8B$fi)$  
oU }eAZj{  
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: IyTL|W6  
1. 在FRED脚本编辑界面找到参考. ^[]G sF  
2. 找到Matlab Automation Server Type Library g\sW2qXEw  
    3. 将名字改为MLAPP qU!*QZ^y&  
     dB{o-R  
     Yh`P+L  
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。 |\g=ua+h

现在将脚本代码公布如下,此脚本执行如下几个步骤: unE h  
1. 创建Matlab服务器。 =nQ"ye  
2. 移动探测面对于前一聚焦面的位置。 " P A:  
3. 在探测面追迹光线 X+l &MD  
4. 在探测面计算照度 /S29\^  
5. 使用PutWorkspaceData发送照度数据到Matlab U\N|hw#f!!  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 F,2)Udim  
7. 用Matlab画出照度数据 2qEm,x'S  
8. 在Matlab计算照度平均值 N?!]^jI,  
9. 返回数据到FRED中 d-%!.,F#W
