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。 1 _A B; ^  
j41)X'MgJ  
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: Y|'0bujr  
enableservice('AutomationServer', true) ;m/h?Y~  
enableservice('AutomationServer')  18(hrj  
A&HN7C%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。 }]dK26pX

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: z%lu%   
1. 在FRED脚本编辑界面找到参考. nRP|Qt7>  
2. 找到Matlab Automation Server Type Library @D?KS;#  
3. 将名字改为MLAPP (8Q0?SZN

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。 kAu-=X

现在将脚本代码公布如下,此脚本执行如下几个步骤: 2)iwAu   
1. 创建Matlab服务器。 &.m.ruab  
2. 移动探测面对于前一聚焦面的位置。 *3uBS2Ld  
3. 在探测面追迹光线 n\-nBrVSf  
4. 在探测面计算照度 fX ^h O+f  
5. 使用PutWorkspaceData发送照度数据到Matlab w^ AY= Fc  
6. 使用PutFullMatrix发送标量场数据到Matlab中 #8Bs15aV  
7. 用Matlab画出照度数据 :,@"I$>*/  
8. 在Matlab计算照度平均值 Ofx]  
9. 返回数据到FRED中 `Z#0kpXk_
