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。 qy|bOl  
Lip#uuuXXN  
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: d&^b=d FDu  
enableservice('AutomationServer', true) ~IZ-:?+S^  
enableservice('AutomationServer') d>f;N+O%  
xVPSL#>  
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。 xCZ_x$bk

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: c';~bYZ  
1. 在FRED脚本编辑界面找到参考. d.f0OhQ  
2. 找到Matlab Automation Server Type Library e]1=&:eX#d  
3. 将名字改为MLAPP 9(]_so24,  
IBNg2Y  
Fizrsr 6%  
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。 *z[vp2 TN

现在将脚本代码公布如下,此脚本执行如下几个步骤: s{dm,|?Jl,  
1. 创建Matlab服务器。 %R$)bGT  
2. 移动探测面对于前一聚焦面的位置。 5x@ U<  
3. 在探测面追迹光线 |&@q$d  
4. 在探测面计算照度 ^X&`YXjuN  
5. 使用PutWorkspaceData发送照度数据到Matlab :Ak^M~6a5  
6. 使用PutFullMatrix发送标量场数据到Matlab中  Z`*V9  
7. 用Matlab画出照度数据 u [qy1M0  
8. 在Matlab计算照度平均值 =\]gL%N-|  
9. 返回数据到FRED中 -=lm`X<:
