FRED案例-FRED如何调用Matlab

q*KAk{kR(v  
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}!PQ#`M  
4R*,VR.K  
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: _Y!IEAU/#  
enableservice('AutomationServer', true) *] (iS  
    enableservice('AutomationServer') he4(hX^  
*8Z32c+C  
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。 626r^c=

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: a =QCp4^  
1. 在FRED脚本编辑界面找到参考. #*}+J3/  
2. 找到Matlab Automation Server Type Library Q;u pau  
    3. 将名字改为MLAPP 8_8l.!~

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。 hQ i2U

现在将脚本代码公布如下,此脚本执行如下几个步骤: 1qch]1 ^G  
1. 创建Matlab服务器。 grYe&(`X  
2. 移动探测面对于前一聚焦面的位置。 ;fJ.8C  
3. 在探测面追迹光线 yw!{MO  
4. 在探测面计算照度 @VBcJ{e,  
5. 使用PutWorkspaceData发送照度数据到Matlab e!Hhs/&!T  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 +H.`MZ=  
7. 用Matlab画出照度数据 ;I*o@x_  
8. 在Matlab计算照度平均值 {FG j]*  
9. 返回数据到FRED中 M{\I8oOg
