[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。 dFA1nn6{  
BC\W`K  
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： k/sfak{Q  
enableservice('AutomationServer', true) gS8+S\2
 
enableservice('AutomationServer') `oH4"9&]k3  
MTKNIv|  
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。 &AWrM{e

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： 53gLz_ee  
1. 在FRED脚本编辑界面找到参考. 2pU'&8  
2. 找到Matlab Automation Server Type Library ]:b52Z  
3. 将名字改为MLAPP EW1,&H

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。 Dh}(B$~Oz+

现在将脚本代码公布如下，此脚本执行如下几个步骤： 9 M%Gnz  
1. 创建Matlab服务器。 O ;[Mi  
2. 移动探测面对于前一聚焦面的位置。 ^i_+ugJX  
3. 在探测面追迹光线 @d^Z^H*Yv  
4. 在探测面计算照度 Y;%LwDC  
5. 使用PutWorkspaceData发送照度数据到Matlab =J)<Nx.gA  
6. 使用PutFullMatrix发送标量场数据到Matlab中
C=]<R<Xy  
7. 用Matlab画出照度数据 6>oc,=MV/  
8. 在Matlab计算照度平均值 1dw{:X=j  
9. 返回数据到FRED中 GBT|1c'i
