[分享]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。 >5Q^9 9V  
Nt`F0 9S  
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： E"9/YWv  
enableservice('AutomationServer', true) %fn'iKCB  
enableservice('AutomationServer') mJ6t.%'d  
9[t]]  
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。 Sah<sb=

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： x[GFX8h(k6  
1. 在FRED脚本编辑界面找到参考. Y0P}KPD  
2. 找到Matlab Automation Server Type Library dK0}% ]i3#

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。  m+72C]9

现在将脚本代码公布如下，此脚本执行如下几个步骤： i#@v_^q  
1. 创建Matlab服务器。 I&'S2=s  
2. 移动探测面对于前一聚焦面的位置。 F- !}

3. 在探测面追迹光线 BRo R"#'  
4. 在探测面计算照度 75hFyh;u  
5. 使用PutWorkspaceData发送照度数据到Matlab MYDf`0{$_a  
6. 使用PutFullMatrix发送标量场数据到Matlab中 WV,?Ge  
7. 用Matlab画出照度数据 |*]X\UE  
8. 在Matlab计算照度平均值 J-eA,9J  
9. 返回数据到FRED中 _-|yCo
