[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。 x1E;dbOZ  
N:+d=G`x  
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： uAoZ&8D6  
enableservice('AutomationServer', true) !3DY#  
enableservice('AutomationServer') 2vsV:LS.  
X2:23j<  
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。 _

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： <Kl$ek8  
1. 在FRED脚本编辑界面找到参考. {5d 5Y%&  
2. 找到Matlab Automation Server Type Library [9MbNJt 8~  
3. 将名字改为MLAPP 7~k=t!gTY

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。 n:k4t

现在将脚本代码公布如下，此脚本执行如下几个步骤： `QW=<Le?  
1. 创建Matlab服务器。 k{UeY[,jb  
2. 移动探测面对于前一聚焦面的位置。 x#R6Ez7  
3. 在探测面追迹光线 _./s[{ek  
4. 在探测面计算照度 d/~g3n>|  
5. 使用PutWorkspaceData发送照度数据到Matlab P$*Ngt  
6. 使用PutFullMatrix发送标量场数据到Matlab中 u-mD"  
7. 用Matlab画出照度数据  vP? T  
8. 在Matlab计算照度平均值 ]H\tz@ &  
9. 返回数据到FRED中 -R\dgS3
