[技术]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。 xgn@1.}G  
1q0DOf]!T  
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： Uh'3c"  
enableservice('AutomationServer', true) r"d/9  
enableservice('AutomationServer') y/k6gl[`  
K??%Qh5l+C  
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。 =hxj B*")  
+[:"$?J  
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： -D?T0>  
1. 在FRED脚本编辑界面找到参考. J3KY?,g3O_  
2. 找到Matlab Automation Server Type Library TCYjj:/  
3. 将名字改为MLAPP B!0o6)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。 c"Kl@[1\~

现在将脚本代码公布如下，此脚本执行如下几个步骤： |b7v(Hx  
1. 创建Matlab服务器。 NNLZ38BV7  
2. 移动探测面对于前一聚焦面的位置。 izy7.(.a  
3. 在探测面追迹光线 /6jt 5N&,  
4. 在探测面计算照度 _TfG-Ae  
5. 使用PutWorkspaceData发送照度数据到Matlab MlaViw  
6. 使用PutFullMatrix发送标量场数据到Matlab中 pp@Jndlg  
7. 用Matlab画出照度数据 Cx2s5vJX4p  
8. 在Matlab计算照度平均值 c ]M!4.  
9. 返回数据到FRED中 k FE2Vv4.
