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。 7^tYtMm|U  
ZsSW{ffZ77  
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: Q]e]\J  
enableservice('AutomationServer', true) *Qyu QF  
enableservice('AutomationServer') ~F%sO'4!  
F}=_"IkZ  
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。 Mfnfp{.)

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: ubRhJ~XB  
1. 在FRED脚本编辑界面找到参考. BS(jC  
2. 找到Matlab Automation Server Type Library cg_ " }]Y1  
3. 将名字改为MLAPP r6GXmr  
S|af?IW  
[5tvdW6Z &  
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。 c\/-*OYr<

现在将脚本代码公布如下,此脚本执行如下几个步骤: F{^\vFp  
1. 创建Matlab服务器。 #+i:s92],  
2. 移动探测面对于前一聚焦面的位置。 6l T< lzT  
3. 在探测面追迹光线 Jg)( F|>o  
4. 在探测面计算照度 (<rE1w2s:  
5. 使用PutWorkspaceData发送照度数据到Matlab  q*94vo-  
6. 使用PutFullMatrix发送标量场数据到Matlab中 /:ZwGyT;  
7. 用Matlab画出照度数据 JY@bD:  
8. 在Matlab计算照度平均值 ^4NRmlb  
9. 返回数据到FRED中 {]dG 9
