[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。 Y0dEH^I  
U-(01-  
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： h-K_Lr]  
enableservice('AutomationServer', true) vDhh>x(  
enableservice('AutomationServer') e>7>j@(K]  
qUW! G&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。 }"P|`"WW

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： oC: {aK6\  
1. 在FRED脚本编辑界面找到参考. S8wLmd>  
2. 找到Matlab Automation Server Type Library L;NvcUFn  
3. 将名字改为MLAPP 7<#U(,YEA

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。 03qQ'pq

现在将脚本代码公布如下，此脚本执行如下几个步骤： 17[3/m8a  
1. 创建Matlab服务器。 I7vz+>Jr  
2. 移动探测面对于前一聚焦面的位置。 s_OF(o  
3. 在探测面追迹光线 BB!THj69a6  
4. 在探测面计算照度 ,,&*:<Q  
5. 使用PutWorkspaceData发送照度数据到Matlab HIR~"It$  
6. 使用PutFullMatrix发送标量场数据到Matlab中 vkx7paY_  
7. 用Matlab画出照度数据 $=8 NED5  
8. 在Matlab计算照度平均值 *K6g\f]b#  
9. 返回数据到FRED中 ]7F=u!/`<C
