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。 Tfytc$aQ  
s +Q'\?  
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: IW>\\&pJ  
enableservice('AutomationServer', true) KvvG H-]  
enableservice('AutomationServer') v(GT+i)|  
Fs_zNN  
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。 qmF+@R&^i  
.  g8WMm  
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: L?&Trq7i  
1. 在FRED脚本编辑界面找到参考. !h.bD/? K  
2. 找到Matlab Automation Server Type Library &0Bs?oq_  
3. 将名字改为MLAPP lHc|: vG?  
+ab#2~,)  
m`!Vryf  
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。 +eVm+4WK

现在将脚本代码公布如下,此脚本执行如下几个步骤: PBY;S G ~  
1. 创建Matlab服务器。 Y{`hRz`  
2. 移动探测面对于前一聚焦面的位置。 W*Gp0pX  
3. 在探测面追迹光线 /zTx+U.\I  
4. 在探测面计算照度 WW3! ,ln_  
5. 使用PutWorkspaceData发送照度数据到Matlab sOBuJx${m  
6. 使用PutFullMatrix发送标量场数据到Matlab中 [E:-$R  
7. 用Matlab画出照度数据 Sd?+j;/"  
8. 在Matlab计算照度平均值 5X}OUn8  
9. 返回数据到FRED中 Wg[ThaZ
