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。 2nz'/G  
IF21T  
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: N`^W*>XB  
enableservice('AutomationServer', true) 6xQe!d3>s3  
enableservice('AutomationServer') pzp"NKx i  
~\(>m=|C:H  
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。 @9Pn(fd]  
x@(f^P  
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: rsj}hS$  
1. 在FRED脚本编辑界面找到参考. !ES#::;z?  
2. 找到Matlab Automation Server Type Library mI*>7?  
3. 将名字改为MLAPP ,Onm!LI=  
(N>ew)Ke

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。 f v7g93

现在将脚本代码公布如下,此脚本执行如下几个步骤: ]cY'6'}Hz  
1. 创建Matlab服务器。 w9h5f  
2. 移动探测面对于前一聚焦面的位置。 "f$A0RL  
3. 在探测面追迹光线 *y@]zNPD  
4. 在探测面计算照度 WmBnc#>gK  
5. 使用PutWorkspaceData发送照度数据到Matlab Sgk{NM7|k  
6. 使用PutFullMatrix发送标量场数据到Matlab中 -]MP,P%  
7. 用Matlab画出照度数据 JO$]t|I  
8. 在Matlab计算照度平均值 -5B([jHgR  
9. 返回数据到FRED中 I z@x^s
