[技术]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。 'e6WDC1Am(  
%RDI!e<e}  
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： J(6oL   
enableservice('AutomationServer', true) :^(>YAyHj^  
enableservice('AutomationServer') p QizJ6  
B7!3-1<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。 \<g*8?yFs

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： [p<w._b i  
1. 在FRED脚本编辑界面找到参考. 8Ac:_Zg  
2. 找到Matlab Automation Server Type Library db6mfxi  
3. 将名字改为MLAPP @*sWu_-Y%

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。 KVJ_E

现在将脚本代码公布如下，此脚本执行如下几个步骤： SCz318n  
1. 创建Matlab服务器。 e2A-;4?_  
2. 移动探测面对于前一聚焦面的位置。 ow]053:i  
3. 在探测面追迹光线 [1u-Q%?#  
4. 在探测面计算照度 (P$H<FtH  
5. 使用PutWorkspaceData发送照度数据到Matlab mWvl38  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ynrT a..  
7. 用Matlab画出照度数据 K1T4cUo  
8. 在Matlab计算照度平均值 6AhM=C  
9. 返回数据到FRED中 <%"b9T`'
