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。 uYG^Pc^v  
neF]=uCWnT  
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: vH %gdpxX  
enableservice('AutomationServer', true) )U<Y0bZA!  
enableservice('AutomationServer') ~|Y>:M+0Z  
X~.f7Ao[  
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。 :VmHfOO

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: V:NI4dv/R  
1. 在FRED脚本编辑界面找到参考. .3pbuU  
2. 找到Matlab Automation Server Type Library \a^,sV  
3. 将名字改为MLAPP 5 LP?Ij

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。 xvLn'8H.

现在将脚本代码公布如下,此脚本执行如下几个步骤: G28O%jD?  
1. 创建Matlab服务器。 DrW#v-d  
2. 移动探测面对于前一聚焦面的位置。 Q-TV*FD.  
3. 在探测面追迹光线 h( QYxI,|  
4. 在探测面计算照度 #b0{#^S:  
5. 使用PutWorkspaceData发送照度数据到Matlab 3B0lb "e  
6. 使用PutFullMatrix发送标量场数据到Matlab中 bEuaOBc  
7. 用Matlab画出照度数据 >"3>s%  
8. 在Matlab计算照度平均值 `ejUs]SR  
9. 返回数据到FRED中 xh@-g|+g
