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。 +K4v"7C V  
)u:8Pv  
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:  C3Z(k}  
enableservice('AutomationServer', true) s0'U[]  
enableservice('AutomationServer') W| eG}`  
oO,p.X%  
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。 PU\q.y0R

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: _e^V\O>  
1. 在FRED脚本编辑界面找到参考. |-?b)yuAz  
2. 找到Matlab Automation Server Type Library _$x *CP0(  
3. 将名字改为MLAPP Z.19v>-c

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。 G4]``

现在将脚本代码公布如下,此脚本执行如下几个步骤: DGUU1 vA  
1. 创建Matlab服务器。 ,*#M%Pv1t  
2. 移动探测面对于前一聚焦面的位置。 Zz ?y&T  
3. 在探测面追迹光线 1&WFs6  
4. 在探测面计算照度 /FXfu  
5. 使用PutWorkspaceData发送照度数据到Matlab \p|!=H@  
6. 使用PutFullMatrix发送标量场数据到Matlab中 }jXUd=.Nu  
7. 用Matlab画出照度数据 V)@scB|>,  
8. 在Matlab计算照度平均值 #@`^  .  
9. 返回数据到FRED中 'S ;vv]}Gs
