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。 jf.ikxm  
~mmI] pC  
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: Hsx`P  
enableservice('AutomationServer', true) 7m@pdq5Ub  
enableservice('AutomationServer') ZN G.W0{p  
.+{nfmc,c  
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。 K6!`b( v#  
 ,ulTZV  
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: ?ew^%1!W.  
1. 在FRED脚本编辑界面找到参考. KC8A22  
2. 找到Matlab Automation Server Type Library nSgg'I(  
3. 将名字改为MLAPP C+-~Gmrb(7  
fs~n{z,ja%  
OuS{ve  
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。 \p [!@d^

现在将脚本代码公布如下,此脚本执行如下几个步骤: +(UrqK4Av  
1. 创建Matlab服务器。 q0DoR@  
2. 移动探测面对于前一聚焦面的位置。 ^x:4%%Q]l  
3. 在探测面追迹光线 P|_?{1eO2  
4. 在探测面计算照度 Gash3}+  
5. 使用PutWorkspaceData发送照度数据到Matlab Y6^lKw  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ~g>15b3  
7. 用Matlab画出照度数据 [9aaHf@'  
8. 在Matlab计算照度平均值 >\(Ma3S   
9. 返回数据到FRED中 YN"102CK
