[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。 O]?PC^GGY  
4@9xq<<5  
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： 3#{Al[jq  
enableservice('AutomationServer', true) cJ'OqV F  
enableservice('AutomationServer') 
{Ok]$0L  
? RID4xu!  
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。 TV?MB(mN

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： "|/Q5*L  
1. 在FRED脚本编辑界面找到参考. {Lsl2@22  
2. 找到Matlab Automation Server Type Library |u#7@&N1  
3. 将名字改为MLAPP ;IR.6k$;

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。 x-~=@oiv

1. 创建Matlab服务器。 X?'pcYSL  
2. 移动探测面对于前一聚焦面的位置。 !d1a9los  
3. 在探测面追迹光线 T1(*dVU?  
4. 在探测面计算照度 fN6n2*wr(  
5. 使用PutWorkspaceData发送照度数据到Matlab

6. 使用PutFullMatrix发送标量场数据到Matlab中 uP^u:'VjbH  
7. 用Matlab画出照度数据 [=^Wj`;  
8. 在Matlab计算照度平均值 pL2{zW`FDh  
9. 返回数据到FRED中 BR:Mcc
