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。 fo <nk|i  
m 0Uu2Z4  
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: =>&~p\Aw  
enableservice('AutomationServer', true) VMS3Q)Ul  
enableservice('AutomationServer') G7KOJZb+D  
oW>e.}d!  
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。 1\AcceJ|(w

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: Fh&USn"  
1. 在FRED脚本编辑界面找到参考. ]vw%J ^7:a  
2. 找到Matlab Automation Server Type Library _bv9/#tR  
3. 将名字改为MLAPP #MviO!@

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。 AbQ nx%$u

现在将脚本代码公布如下,此脚本执行如下几个步骤: iszVM  
1. 创建Matlab服务器。 };'~@%U]/  
2. 移动探测面对于前一聚焦面的位置。 ]4'V59\  
3. 在探测面追迹光线 y>cT{)E$  
4. 在探测面计算照度 !, sQB_09C  
5. 使用PutWorkspaceData发送照度数据到Matlab %6&c3,?U\n  
6. 使用PutFullMatrix发送标量场数据到Matlab中 W@+ge]9m&  
7. 用Matlab画出照度数据 67||wh.BU  
8. 在Matlab计算照度平均值 H2+V1J=  
9. 返回数据到FRED中 =(bTS n
