[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。 "9QZX[J|*  
!o?&{"#+  
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： )R'%SLw  
enableservice('AutomationServer', true) K\fD';  
enableservice('AutomationServer') jN*w
bqL  
.[1 f$  
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。 U5~aG!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： +>*=~R
 
1. 在FRED脚本编辑界面找到参考. )AR-b8..o  
2. 找到Matlab Automation Server Type Library Tsb}\  
3. 将名字改为MLAPP \#Jq%nd

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。 '/6f2[%Y"

1. 创建Matlab服务器。 41Q)w=hoN  
2. 移动探测面对于前一聚焦面的位置。 % 33O)<?  
3. 在探测面追迹光线 B;NK\5>  
4. 在探测面计算照度 .$W}  
5. 使用PutWorkspaceData发送照度数据到Matlab $/g`{OI]K  
6. 使用PutFullMatrix发送标量场数据到Matlab中 gzSm=6Qw0  
7. 用Matlab画出照度数据 RHNAHw9  
8. 在Matlab计算照度平均值 LiQH!yHW  
9. 返回数据到FRED中 [hg9 0Q6
