FRED案例-FRED如何调用Matlab

!K2QD[x  
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。 a6A~,68/V  
,y-!h@(  
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: JbitRV@a  
enableservice('AutomationServer', true) 'ahZ*@kr  
    enableservice('AutomationServer') ?MfwRWY  
.F%jbnKd_  
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。 OXl0R{4

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: C]3:&dx9  
1. 在FRED脚本编辑界面找到参考. T#:b  
2. 找到Matlab Automation Server Type Library `PeC,bp  
    3. 将名字改为MLAPP a-nn[ j

     LOG>x!  
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。 B+jh|@-

现在将脚本代码公布如下,此脚本执行如下几个步骤: n _x+xVi%  
1. 创建Matlab服务器。 L&=r-\.ev  
2. 移动探测面对于前一聚焦面的位置。 '6g-]rE[  
3. 在探测面追迹光线 Y]`o-dV  
4. 在探测面计算照度 92C; a5s  
5. 使用PutWorkspaceData发送照度数据到Matlab rf`xY4I\  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 VV 54$a  
7. 用Matlab画出照度数据 +~P_o_M  
8. 在Matlab计算照度平均值 zK_P3r LsS  
9. 返回数据到FRED中 C CLc,r>)
