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。 a ykNH>#Po  
b1A8 -![  
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: u\-f\Z7  
enableservice('AutomationServer', true) kN)m"}gX  
enableservice('AutomationServer') =Qcz:ng  
Jm+hDZrW  
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。 T"2D<7frbo

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: liUrw7,  
1. 在FRED脚本编辑界面找到参考. MOIH%lpe  
2. 找到Matlab Automation Server Type Library . d;XLS~  
3. 将名字改为MLAPP IaU  
mt+IB4`  
N:y3tpG  
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。 #.(6.Li

现在将脚本代码公布如下,此脚本执行如下几个步骤: JRm:hf'  
1. 创建Matlab服务器。 ">G|\_ZF  
2. 移动探测面对于前一聚焦面的位置。 <[H1S@{W  
3. 在探测面追迹光线 0r?}LWjf  
4. 在探测面计算照度 w6fVZY4  
5. 使用PutWorkspaceData发送照度数据到Matlab XZv(B^  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ;-d }\f ,  
7. 用Matlab画出照度数据  pv=g)  
8. 在Matlab计算照度平均值 0wLu*K5$4E  
9. 返回数据到FRED中 (=H%VXQH
