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。 nV?e(}D  
yI}_ U  
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: w_^g-P[o-  
enableservice('AutomationServer', true) mX QVL.P\  
enableservice('AutomationServer') -hpMd/F  
C-L["O0[  
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。 HXRK<6k$  
<}^l MBa  
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: tU(vt0~b  
1. 在FRED脚本编辑界面找到参考. vhu5w#]u*  
2. 找到Matlab Automation Server Type Library [}=/?(5  
3. 将名字改为MLAPP Lw #vHNf6

/*) =o+  
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。 \J3n[6;

现在将脚本代码公布如下,此脚本执行如下几个步骤: =;@?bTmqD  
1. 创建Matlab服务器。 {,b:f  
2. 移动探测面对于前一聚焦面的位置。 7Ys\=W1  
3. 在探测面追迹光线 {w|KWGk2  
4. 在探测面计算照度 <ooRpn  
5. 使用PutWorkspaceData发送照度数据到Matlab 4 | DGQ  
6. 使用PutFullMatrix发送标量场数据到Matlab中 9='=wWW  
7. 用Matlab画出照度数据 U4$CkTe2Y  
8. 在Matlab计算照度平均值 6?(vXPpT$  
9. 返回数据到FRED中 z2.ZxL"*
