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。 D->E&#  
jX'pUO  
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: `ba<eT':  
enableservice('AutomationServer', true) ;j;U9-oh  
enableservice('AutomationServer') v@2?X4n  
B ( h`~pb  
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。 gjK: a@{

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: S+6YD0  
1. 在FRED脚本编辑界面找到参考. X_JC1  
2. 找到Matlab Automation Server Type Library c uAp,!  
3. 将名字改为MLAPP d_:tiHw$

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。 3- d"-'k

现在将脚本代码公布如下,此脚本执行如下几个步骤: j _E(h.  
1. 创建Matlab服务器。 >4>. Ycp  
2. 移动探测面对于前一聚焦面的位置。 -"^"& )  
3. 在探测面追迹光线 ,-$%>Uv   
4. 在探测面计算照度 {az LtTh  
5. 使用PutWorkspaceData发送照度数据到Matlab } -hH2  
6. 使用PutFullMatrix发送标量场数据到Matlab中 h9c7P@29  
7. 用Matlab画出照度数据 m^0*k|9+G  
8. 在Matlab计算照度平均值 [A!=Hv_$  
9. 返回数据到FRED中 '@hnqcqXq
