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。 O%tlj@?  
b@Ik c<  
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: R5r )01  
enableservice('AutomationServer', true) \QBODJ1  
enableservice('AutomationServer') HpSgGhL'J&  
@GBS-iT3  
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。 Od^y&$|_%`

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: `T{{wty  
1. 在FRED脚本编辑界面找到参考. >VE,/?71@  
2. 找到Matlab Automation Server Type Library u#\=g:  
3. 将名字改为MLAPP j S')!Wcu

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。 @PZ&/F ^

现在将脚本代码公布如下,此脚本执行如下几个步骤: J1 a/U@"  
1. 创建Matlab服务器。  ;B^G<  
2. 移动探测面对于前一聚焦面的位置。 x!{5.#  
3. 在探测面追迹光线 I6M 7xn  
4. 在探测面计算照度 6sRn_y  
5. 使用PutWorkspaceData发送照度数据到Matlab Cl6y:21]K  
6. 使用PutFullMatrix发送标量场数据到Matlab中 { e<J}-/?  
7. 用Matlab画出照度数据 G=jdb@V/?  
8. 在Matlab计算照度平均值 &0It"17Ej  
9. 返回数据到FRED中 9<.FwV >
