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。 Bi +a)_K  
B !hrr  
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: AwKxt'()^  
enableservice('AutomationServer', true) I2!0,1Q  
enableservice('AutomationServer') Q(}TN,N  
fi[c^e+IX  
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。 k_=~ObA$g  
h69: Tj!  
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: fQ&:1ec  
1. 在FRED脚本编辑界面找到参考. ;NrkX?Y  
2. 找到Matlab Automation Server Type Library Cz\(.MWNZ  
3. 将名字改为MLAPP QrP$5H{[E  
@ P=eu3  
cs?@Ri=g  
在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 ]x hmM1$

现在将脚本代码公布如下,此脚本执行如下几个步骤: O/IW.t  
1. 创建Matlab服务器。 V;Zp3Qo!  
2. 移动探测面对于前一聚焦面的位置。 @5%cP  
3. 在探测面追迹光线 dQ8}mH!  
4. 在探测面计算照度 6t5)rlT  
5. 使用PutWorkspaceData发送照度数据到Matlab N.q4Ar[x#p  
6. 使用PutFullMatrix发送标量场数据到Matlab中 N[j7^q7Xt  
7. 用Matlab画出照度数据 Qr;es,f  
8. 在Matlab计算照度平均值 62}bs/%  
9. 返回数据到FRED中 &/J[PdSb$
