[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。 E}4R[6YD  
B!rY\ ?W  
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： 0FH
N  
enableservice('AutomationServer', true) o{nBtxZ"  
enableservice('AutomationServer') lYD-
U8  
#L[Atx  
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。 =d&  
</Q<*@p?  
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： OG/R6k.  
1. 在FRED脚本编辑界面找到参考. oM Q+=  
2. 找到Matlab Automation Server Type Library _q+H>1.&9  
3. 将名字改为MLAPP ~b\bpu

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。 2NqlE

现在将脚本代码公布如下，此脚本执行如下几个步骤： 3Sf<oYF  
1. 创建Matlab服务器。 Z[Uz~W6M]  
2. 移动探测面对于前一聚焦面的位置。 R\ <HR9r  
3. 在探测面追迹光线 l<!?`V6}  
4. 在探测面计算照度 >t3%-Kc  
5. 使用PutWorkspaceData发送照度数据到Matlab ?0Z?Z3)%w4  
6. 使用PutFullMatrix发送标量场数据到Matlab中 h@@2vs2  
7. 用Matlab画出照度数据 7_ZfV? .  
8. 在Matlab计算照度平均值 \:%e 6M  
9. 返回数据到FRED中 g]N!_Ib/!
