[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。 zGtWyXP

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：  V6opV&  
enableservice('AutomationServer', true) } 0su[gy[  
enableservice('AutomationServer') =og5Mh,  
JmHEYPt0  
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。 [PVem

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： TqzL]'NS+  
1. 在FRED脚本编辑界面找到参考. S8+G
M  
2. 找到Matlab Automation Server Type Library i98>=y~  
3. 将名字改为MLAPP r_m*$r~f

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。  58S>B'

现在将脚本代码公布如下，此脚本执行如下几个步骤： fk*$}f  
1. 创建Matlab服务器。 TR@*tfS  
2. 移动探测面对于前一聚焦面的位置。 |=R@nn   
3. 在探测面追迹光线 :Q~Rb<']{x  
4. 在探测面计算照度 %}T' 3  
5. 使用PutWorkspaceData发送照度数据到Matlab "x;|li3;  
6. 使用PutFullMatrix发送标量场数据到Matlab中 BU3VXnqT[  
7. 用Matlab画出照度数据 :Z

8. 在Matlab计算照度平均值 ^0 zWiX  
9. 返回数据到FRED中 <4l;I*:2&
