[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。 ?FAI@

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： kJ_8|  
enableservice('AutomationServer', true) rKrHd  
enableservice('AutomationServer') '*b]$5*p  
h<LFTYE@  
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。 + t5SrO!`

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： AzOs/q8O  
1. 在FRED脚本编辑界面找到参考. (jc& F
k  
2. 找到Matlab Automation Server Type Library {p84fR1P  
3. 将名字改为MLAPP hWT jN

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。 "r-P[EKpL

现在将脚本代码公布如下，此脚本执行如下几个步骤： n:%4SZn  
1. 创建Matlab服务器。 5G f@n/M"  
2. 移动探测面对于前一聚焦面的位置。 u=.8

3. 在探测面追迹光线 aj1]ZT\  
4. 在探测面计算照度 *5%vU|9b  
5. 使用PutWorkspaceData发送照度数据到Matlab 4 O!2nP  
6. 使用PutFullMatrix发送标量场数据到Matlab中 C!VhVOy>d  
7. 用Matlab画出照度数据 lvO6&sF1  
8. 在Matlab计算照度平均值 #J"xByQKK  
9. 返回数据到FRED中 0X=F(,>9
