[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。 kMEXgzl  
d=vD Pf  
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： Ya<KMBi3  
enableservice('AutomationServer', true) ?0z/i^I  
enableservice('AutomationServer') J- l[dC  
 +
+8 Xi1  
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。 NX;{L#lQ

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： 7:$dl#  
1. 在FRED脚本编辑界面找到参考. WoSKN7*  
2. 找到Matlab Automation Server Type Library F$:mGyl5_  
3. 将名字改为MLAPP w+\RSqz/

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。 V0#E7u`4

现在将脚本代码公布如下，此脚本执行如下几个步骤： 5(Q-||J  
1. 创建Matlab服务器。 l`j@QP  
2. 移动探测面对于前一聚焦面的位置。 ^ 6t"A  
3. 在探测面追迹光线 Ia^/^>  
4. 在探测面计算照度 `C6,**`R$k  
5. 使用PutWorkspaceData发送照度数据到Matlab cZWW[i  
6. 使用PutFullMatrix发送标量场数据到Matlab中 $x+ P)5)  
7. 用Matlab画出照度数据 r|3u]rt  
8. 在Matlab计算照度平均值 5':j=KQE_  
9. 返回数据到FRED中 q7rX4-G$
