[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。 e{Y8m Xu  
t}Q PPp y  
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： 6f'THU$  
enableservice('AutomationServer', true) =Hd+KvA  
enableservice('AutomationServer') #0*oj/  
r%uka5@  
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。 V*I2

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： 2(i@\dZCb<  
1. 在FRED脚本编辑界面找到参考. W2w A66MB  
2. 找到Matlab Automation Server Type Library

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。 NI^jQS M]

1. 创建Matlab服务器。 ">M:6\B  
2. 移动探测面对于前一聚焦面的位置。 F&_b[xso7  
3. 在探测面追迹光线 n8.Tag(#  
4. 在探测面计算照度 .At^b4#(  
5. 使用PutWorkspaceData发送照度数据到Matlab -Q MO*PY  
6. 使用PutFullMatrix发送标量场数据到Matlab中 6k6}SlN[  
7. 用Matlab画出照度数据 DX(!G a  
8. 在Matlab计算照度平均值 3+WmM4|  
9. 返回数据到FRED中 F@ld#O
