[技术]FRED如何调用Matlab [复制链接]

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。 ow;R$5G  
%77p5ctW  
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： 9 ASb>A2~  
enableservice('AutomationServer', true) oM1 6C|  
enableservice('AutomationServer') EIbXmkHl<  
";w}3+R  
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。 m&0"<V!H/B

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： }o,z!_^PLQ  
1. 在FRED脚本编辑界面找到参考. ^t*x*m8  
2. 找到Matlab Automation Server Type Library w_4]xgS:  
3. 将名字改为MLAPP 9>#:/g/  
b2&V

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。 &>jAe_{",

现在将脚本代码公布如下，此脚本执行如下几个步骤： Lj%{y.Rj  
1. 创建Matlab服务器。 m:O(+Fl  
2. 移动探测面对于前一聚焦面的位置。 sK=}E=  
3. 在探测面追迹光线 X0+fsf<H}  
4. 在探测面计算照度 k)FmDX  
5. 使用PutWorkspaceData发送照度数据到Matlab - ?!:{UXl  
6. 使用PutFullMatrix发送标量场数据到Matlab中 68'>Zbelb  
7. 用Matlab画出照度数据 DV]7.Bm  
8. 在Matlab计算照度平均值 +f;CyMEp  
9. 返回数据到FRED中 TE-;X,gDV_
