FRED如何调用Matlab

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。 FG{,l=Z0  
7&wxnxSk^  
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: 1KGf @u%-1  
enableservice('AutomationServer', true) o _l_Yi  
enableservice('AutomationServer') B8"c+<b  
!sEhjJV^7  
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。 L(cKyg[R  
}F/w34+;  
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: _?cum ~A@  
1. 在FRED脚本编辑界面找到参考. (n: A` ]  
2. 找到Matlab Automation Server Type Library #Y3-P  
3. 将名字改为MLAPP ot2zY dWAz  
?PTXgIC  
,dK)I1"C  
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。 yocFdI

现在将脚本代码公布如下,此脚本执行如下几个步骤: .K(9=yh  
1. 创建Matlab服务器。 g[t paQ  
2. 移动探测面对于前一聚焦面的位置。 [q3zs_nz  
3. 在探测面追迹光线 cuumQQ  
4. 在探测面计算照度 5p}j{f  
5. 使用PutWorkspaceData发送照度数据到Matlab m%[/w wL  
6. 使用PutFullMatrix发送标量场数据到Matlab中 nh5=0{va|L  
7. 用Matlab画出照度数据 yp^k;G?_d  
8. 在Matlab计算照度平均值 ABe25Sus  
9. 返回数据到FRED中 {r;_nMfH|[
