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。 l Zz%W8"  
F T$x#>  
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: z5 g4+y,  
enableservice('AutomationServer', true) =`OnFdI  
enableservice('AutomationServer') 9#:B_?e=  
s(8e)0Tl  
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。 %hVI*p3

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: uhvn1"  
1. 在FRED脚本编辑界面找到参考. oqa8v6yG'  
2. 找到Matlab Automation Server Type Library l&_PsnU  
3. 将名字改为MLAPP A(D3wctdr  
H Xb_k1n

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。 Zo#c[9IaC

现在将脚本代码公布如下,此脚本执行如下几个步骤: TlC GP)VSj  
1. 创建Matlab服务器。 b6d}<b9#  
2. 移动探测面对于前一聚焦面的位置。 7_~_$I~g*  
3. 在探测面追迹光线 V$g!#V  
4. 在探测面计算照度 {.r #j|  
5. 使用PutWorkspaceData发送照度数据到Matlab 6 2LLfD  
6. 使用PutFullMatrix发送标量场数据到Matlab中 rCd*'Qg  
7. 用Matlab画出照度数据 K6 c[W%Va  
8. 在Matlab计算照度平均值 i$6o>V6  
9. 返回数据到FRED中 ^[.Z~>3!\q
