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。 jlM %Y ZC  
JPmZ%]wA  
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: r34 GO1d  
enableservice('AutomationServer', true) eCy]ugsi%  
enableservice('AutomationServer') IWNIk9T,u  
a-Ne!M[  
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。 gMB/ ~g5b0

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: #(dERET*  
1. 在FRED脚本编辑界面找到参考. <xaB$}R  
2. 找到Matlab Automation Server Type Library [h@MA|  
3. 将名字改为MLAPP x67,3CLy?

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。 Mw{skK>b

现在将脚本代码公布如下,此脚本执行如下几个步骤: EC f $  
1. 创建Matlab服务器。 0qk.NPMB0  
2. 移动探测面对于前一聚焦面的位置。 -) \!@n0  
3. 在探测面追迹光线 aj6{  
4. 在探测面计算照度 hZDv5]V:0  
5. 使用PutWorkspaceData发送照度数据到Matlab _^Lg}@t  
6. 使用PutFullMatrix发送标量场数据到Matlab中 S X6P>:`  
7. 用Matlab画出照度数据 d A' h7D  
8. 在Matlab计算照度平均值 *+>R^\uT  
9. 返回数据到FRED中 ]qNPOnlp
