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。 .dqV fa  
R0|dKKzS  
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: ?Ybgzb  
enableservice('AutomationServer', true) <7-Qn(m,  
enableservice('AutomationServer') oT9dMhx8  
h+ixl#:  
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。 RE~9L5i5  
z^;0{q,  
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: ?4p\ujc  
1. 在FRED脚本编辑界面找到参考. l\+^.ezD  
2. 找到Matlab Automation Server Type Library KY}c}*0  
3. 将名字改为MLAPP 2Fwp\I;

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。 3QNu7oo

现在将脚本代码公布如下,此脚本执行如下几个步骤: S.G"*'N  
1. 创建Matlab服务器。 }.+{M.[}  
2. 移动探测面对于前一聚焦面的位置。 M1UabqQ  
3. 在探测面追迹光线 njhDrwN  
4. 在探测面计算照度 )w3?o#@  
5. 使用PutWorkspaceData发送照度数据到Matlab 5%`fh%  
6. 使用PutFullMatrix发送标量场数据到Matlab中 zn!H&!8&  
7. 用Matlab画出照度数据 .K I6<k/  
8. 在Matlab计算照度平均值 W|C>X=zTi  
9. 返回数据到FRED中 J3 Y-d7=|
