[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。 3'I^lc  
[0;buVU.  
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： ]`o!1(GA  
enableservice('AutomationServer', true) 4`v!Z#e/aX  
enableservice('AutomationServer') @tT-JwU  
d5m`Bm-{  
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。 WrGK

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： K?.e|  
1. 在FRED脚本编辑界面找到参考. .IrNa>J

2. 找到Matlab Automation Server Type Library H=c`&N7E  
3. 将名字改为MLAPP 2)0b2QbQ

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。 MN8H;0g-

现在将脚本代码公布如下，此脚本执行如下几个步骤： _=f=fcl  
1. 创建Matlab服务器。 |F$BvCg  
2. 移动探测面对于前一聚焦面的位置。

3. 在探测面追迹光线 " {dek  
4. 在探测面计算照度 PD[z#T!'  
5. 使用PutWorkspaceData发送照度数据到Matlab +g*k*e>l  
6. 使用PutFullMatrix发送标量场数据到Matlab中 K`%tGVY  
7. 用Matlab画出照度数据 -.I4-6~  
8. 在Matlab计算照度平均值 R`'1t3p0i  
9. 返回数据到FRED中 %Q
