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。 B7cXbUAQs  
9T)-|fja_  
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: vuHqOAFNs  
enableservice('AutomationServer', true) RK|C*TCnl  
enableservice('AutomationServer') [-Dx)N  
]2?t $"G8  
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。 5@?P 8  
Iu=iC.50}  
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: 1%H]2@  
1. 在FRED脚本编辑界面找到参考. -FwOX~s/'  
2. 找到Matlab Automation Server Type Library `C,479~J  
3. 将名字改为MLAPP A%pcPzG;  
_Y=>^K]9K

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。 H.*XoktC]

现在将脚本代码公布如下,此脚本执行如下几个步骤: 2-FL&DE  
1. 创建Matlab服务器。 c{z QX0  
2. 移动探测面对于前一聚焦面的位置。 phd,Jg[  
3. 在探测面追迹光线 NeQ/#[~g  
4. 在探测面计算照度 5Osx__6$t  
5. 使用PutWorkspaceData发送照度数据到Matlab awGI|d  
6. 使用PutFullMatrix发送标量场数据到Matlab中 o@vo,JU  
7. 用Matlab画出照度数据 L'.7V ~b{  
8. 在Matlab计算照度平均值 LJ9^:U  
9. 返回数据到FRED中 + Uq$'2CT
