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。 M,Lq4bz  
";n%^I}  
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: j1ap,<\.k  
enableservice('AutomationServer', true) 7CX5pRNL  
enableservice('AutomationServer') =~dsIG  
'w|N} 4  
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。 7&V3f=aj6

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: ;BHIss7  
1. 在FRED脚本编辑界面找到参考. ZMK1V)ohn  
2. 找到Matlab Automation Server Type Library i2LN`5k  
3. 将名字改为MLAPP +>% AG&Pc

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。 ^vOEG;TR<-

现在将脚本代码公布如下,此脚本执行如下几个步骤: H;FzWcm  
1. 创建Matlab服务器。 iciRlx.$c  
2. 移动探测面对于前一聚焦面的位置。 t Q>/1  
3. 在探测面追迹光线 Imo?)dYK  
4. 在探测面计算照度 (W9 K: ]}  
5. 使用PutWorkspaceData发送照度数据到Matlab !~-@sq  
6. 使用PutFullMatrix发送标量场数据到Matlab中 @DAaCF8  
7. 用Matlab画出照度数据 8,B#W#*{  
8. 在Matlab计算照度平均值 \@_?mL@=  
9. 返回数据到FRED中 F@ZB6~T~.
