FRED案例-FRED如何调用Matlab

#?@k=e\  
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。 WW:@%cQ@  
Y 'Yoc  
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:  =SRp  
enableservice('AutomationServer', true) S"!nM]2L  
    enableservice('AutomationServer') l=Jbuc  
|z<E%`u%  
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。 2w$o;zz1

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: ;4z6="<Y  
1. 在FRED脚本编辑界面找到参考. _Su? VxU  
2. 找到Matlab Automation Server Type Library W=M]1hy  
    3. 将名字改为MLAPP 8*V3g_z  
     $-|`#|CBd  
     Zoh2m`6  
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。 t9Ht 5 4

现在将脚本代码公布如下,此脚本执行如下几个步骤: Sy6Y3 ~7  
1. 创建Matlab服务器。 O'Lgb9  
2. 移动探测面对于前一聚焦面的位置。 SaH0YxnY+  
3. 在探测面追迹光线 iN %kF'&9  
4. 在探测面计算照度 ]S[M]-I  
5. 使用PutWorkspaceData发送照度数据到Matlab WtN o@e'  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 c_s=>z  
7. 用Matlab画出照度数据 7H:1c=U  
8. 在Matlab计算照度平均值 u}W R1u [  
9. 返回数据到FRED中 2ro4{^(_
