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。 G#1GXFDO{  
L_s:l9!r  
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: hpJ-r  
enableservice('AutomationServer', true) :j`s r  
enableservice('AutomationServer') D,ln)["xm  
W}1 ;Z(.*  
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。 fxIf|9Qi`  
w`=\5Oa.G  
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: 2Hv+W-6v  
1. 在FRED脚本编辑界面找到参考. 3[f): u3"  
2. 找到Matlab Automation Server Type Library 8sCv]|cn  
3. 将名字改为MLAPP ei{eTp4HpV  
cs'{5!i]  
v9->nVc-  
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。 V470C@

现在将脚本代码公布如下,此脚本执行如下几个步骤: $tS}LN_!  
1. 创建Matlab服务器。 NgCvVWto  
2. 移动探测面对于前一聚焦面的位置。 kSh( u  
3. 在探测面追迹光线 _/K_[w 1  
4. 在探测面计算照度 AzxXB  
5. 使用PutWorkspaceData发送照度数据到Matlab })?GzblI&  
6. 使用PutFullMatrix发送标量场数据到Matlab中 8&aq/4:q0  
7. 用Matlab画出照度数据 {.\TtE  
8. 在Matlab计算照度平均值 eGHaY4|  
9. 返回数据到FRED中 JO< wU
