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。 s3J$+1M >  
{ SV$fl;  
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: ?L^ Gu ]y  
enableservice('AutomationServer', true) d yd_dK/  
enableservice('AutomationServer') 4hIC&W~f  
f$|v  
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。 >nX'RE|F  
zVu}7v()  
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: P6Ei!t,>  
1. 在FRED脚本编辑界面找到参考. }_ E  
2. 找到Matlab Automation Server Type Library /l L*U  
3. 将名字改为MLAPP =#fqFL,

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。 ,P^"X5$

现在将脚本代码公布如下,此脚本执行如下几个步骤: %:lQ ~yn  
1. 创建Matlab服务器。 e 6*=Si}V  
2. 移动探测面对于前一聚焦面的位置。 ''G @n*  
3. 在探测面追迹光线 sZc<h]L(g  
4. 在探测面计算照度 3?:}lY<,  
5. 使用PutWorkspaceData发送照度数据到Matlab ~&kV  
6. 使用PutFullMatrix发送标量场数据到Matlab中 m`Z4#_s2  
7. 用Matlab画出照度数据 i|*:gH  
8. 在Matlab计算照度平均值 rlD@O~P4  
9. 返回数据到FRED中 y03l_E,
