[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。 FG-L0X
 
4Yjx{5QSAG  
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： xF
Fr  
enableservice('AutomationServer', true) 3Rv7Qx  
enableservice('AutomationServer') lE#m]D  
,"?A2n-qO  
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。 f-RK,#

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： 8Jr?ZDf`  
1. 在FRED脚本编辑界面找到参考. w!3>N"em  
2. 找到Matlab Automation Server Type Library cPF<D$B  
3. 将名字改为MLAPP 5\4g>5PD

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。 ~6[*q~B

现在将脚本代码公布如下，此脚本执行如下几个步骤： `)>7)={  
1. 创建Matlab服务器。 3.R#&Zxt  
2. 移动探测面对于前一聚焦面的位置。 dE=Ue#1U@5  
3. 在探测面追迹光线  Qo

4. 在探测面计算照度 ]F*3"y?)2  
5. 使用PutWorkspaceData发送照度数据到Matlab i76 Yo5  
6. 使用PutFullMatrix发送标量场数据到Matlab中 c+' =hR[  
7. 用Matlab画出照度数据 oR#:NtX

8. 在Matlab计算照度平均值 woOy*)@  
9. 返回数据到FRED中 %Z]'!X
