[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。 =}[V69a  
@`yfft  
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： d=pq+  
enableservice('AutomationServer', true) 8b/yT4f  
enableservice('AutomationServer') Q1rwTg\  
;Baf&xK  
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。 >jcNo3S

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： ~kL":C>2  
1. 在FRED脚本编辑界面找到参考. ]=/f`  
2. 找到Matlab Automation Server Type Library R[z6 c)  
3. 将名字改为MLAPP 4%pvw;r

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。 sbVeB%k

现在将脚本代码公布如下，此脚本执行如下几个步骤： h*Ej}_  
1. 创建Matlab服务器。 i^8Zp;O"f  
2. 移动探测面对于前一聚焦面的位置。 q+z,{K  
3. 在探测面追迹光线 ~7*HZ:.  
4. 在探测面计算照度 /{lls2ycW%  
5. 使用PutWorkspaceData发送照度数据到Matlab k3Y>QN|q8  
6. 使用PutFullMatrix发送标量场数据到Matlab中 3wK)vW  
7. 用Matlab画出照度数据 yF*

8. 在Matlab计算照度平均值 -V\33cA  
9. 返回数据到FRED中 cNHNh[ C
