[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。 ZY$@_DOB}  
|9Ks13?Ck  
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： gi@ji-10  
enableservice('AutomationServer', true)  WPKTX,k  
enableservice('AutomationServer') HWOs@!cL  
?
u!AHSr(  
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。 K/m)f#

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： X$Vz  
1. 在FRED脚本编辑界面找到参考. +J8/,d  
2. 找到Matlab Automation Server Type Library cY'To<v  
3. 将名字改为MLAPP `h5eej&s(

bMOM`At>z  
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-^%g[#

现在将脚本代码公布如下，此脚本执行如下几个步骤： E816YS='  
1. 创建Matlab服务器。 *u;">H*BW  
2. 移动探测面对于前一聚焦面的位置。 ww t()  
3. 在探测面追迹光线 giPo;z\c  
4. 在探测面计算照度 zo7XmUI3P  
5. 使用PutWorkspaceData发送照度数据到Matlab %i -X@.P  
6. 使用PutFullMatrix发送标量场数据到Matlab中 X>Xp&o  
7. 用Matlab画出照度数据 Y!1^@;)^  
8. 在Matlab计算照度平均值 2*q: ^  
9. 返回数据到FRED中 X$|TN+Ub
