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。 )^'wcBod,  
dkbKnY&  
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: iAW oKW  
enableservice('AutomationServer', true) hO:X\:G  
enableservice('AutomationServer') 0b}lwo,|\  
4^B:Q9B)  
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。 ~9ILN~91

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: LvS3c9|Aj  
1. 在FRED脚本编辑界面找到参考. Jh:-<xy)  
2. 找到Matlab Automation Server Type Library :ui1]its4  
3. 将名字改为MLAPP Yui:=GgUrr

[G|2m_  
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。 c5rQkDW

现在将脚本代码公布如下,此脚本执行如下几个步骤: I@q>ES!1H  
1. 创建Matlab服务器。 y]\R0lR  
2. 移动探测面对于前一聚焦面的位置。 XT_BiZ%l5O  
3. 在探测面追迹光线 Xl*-A|:j  
4. 在探测面计算照度 vR~*r6hX8  
5. 使用PutWorkspaceData发送照度数据到Matlab fhn0^Qc"+  
6. 使用PutFullMatrix发送标量场数据到Matlab中 RN:#+S(8  
7. 用Matlab画出照度数据 (A &@ <  
8. 在Matlab计算照度平均值 [%nG_np  
9. 返回数据到FRED中 JnY3]
