[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。 $Qx(aWE0  
#
d7)$ub  
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： 3|z;K,`Fw  
enableservice('AutomationServer', true) O&gy(  
enableservice('AutomationServer') x`j_d:C~G  
%'K+$  
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。 {|t?

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： /i7>&ND.r  
1. 在FRED脚本编辑界面找到参考. X"]mR7k  
2. 找到Matlab Automation Server Type Library _.s\qQ  
3. 将名字改为MLAPP ,cl"1>lp

-NI@xJO4(;  
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。  xLGTnMYd

现在将脚本代码公布如下，此脚本执行如下几个步骤： g/J^K*3]  
1. 创建Matlab服务器。 j

2. 移动探测面对于前一聚焦面的位置。 -f 'q  
3. 在探测面追迹光线 rK0|9^i{  
4. 在探测面计算照度 ,sy/rV  
5. 使用PutWorkspaceData发送照度数据到Matlab ^O,6(@>  
6. 使用PutFullMatrix发送标量场数据到Matlab中 g tSHy*3]  
7. 用Matlab画出照度数据 NR@SDW  
8. 在Matlab计算照度平均值 ]"7El;2z  
9. 返回数据到FRED中 -qr:c9\px
