[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。 [wHGt?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： /_yJ;l/K  
enableservice('AutomationServer', true) vumA W*  
enableservice('AutomationServer') $9LI v  
3[*E>:)qh  
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。 ;onhc*{lv

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： PNNY_t +I  
1. 在FRED脚本编辑界面找到参考. jIpc^iu`,  
2. 找到Matlab Automation Server Type Library Yz6+ x]  
3. 将名字改为MLAPP g9N_s,3jC

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。 }:6$5/?

1. 创建Matlab服务器。 =t,}I\_^c  
2. 移动探测面对于前一聚焦面的位置。 ?4G/f<ou  
3. 在探测面追迹光线 S5a?KU
  
4. 在探测面计算照度 ((Jiv=%  
5. 使用PutWorkspaceData发送照度数据到Matlab $F^p5EXkc6  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ~hx__^]d  
7. 用Matlab画出照度数据 ak_&\'P  
8. 在Matlab计算照度平均值 aJAQ G  
9. 返回数据到FRED中 ()Cw;N{E
