[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。 Funep[rA  
6|t4\'  
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： R}a,.C  
enableservice('AutomationServer', true) l)fF)\|;=  
enableservice('AutomationServer') -@-cG\{  
r@0HqZx`  
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。 /NaIMo5

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： .0S.7w3dZo  
1. 在FRED脚本编辑界面找到参考. SJ;u,XyWn  
2. 找到Matlab Automation Server Type Library a-,!K  
3. 将名字改为MLAPP 2GA6@-u\

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。 %p)6m2Sb

现在将脚本代码公布如下，此脚本执行如下几个步骤： B@` 87  
1. 创建Matlab服务器。 xWD=",0+  
2. 移动探测面对于前一聚焦面的位置。 `h/j3fmX?  
3. 在探测面追迹光线 mdR:XuRD"t  
4. 在探测面计算照度 8E"Ik~  
5. 使用PutWorkspaceData发送照度数据到Matlab f@T/^|`mh  
6. 使用PutFullMatrix发送标量场数据到Matlab中 =O1N*'

7. 用Matlab画出照度数据 Ey=
