[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。 u~ F;xQ  
6DSH`-;  
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： :_dICxaLZT  
enableservice('AutomationServer', true) ,i`h x, Rg  
enableservice('AutomationServer') `
QP ~  
y)J(K*x/$  
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。 ]Nk!4"

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： hY\{|  
1. 在FRED脚本编辑界面找到参考. J0<p4%Cf  
2. 找到Matlab Automation Server Type Library E%k7wM {  
3. 将名字改为MLAPP f$xhb3Qn

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。 -]"T^wib

现在将脚本代码公布如下，此脚本执行如下几个步骤： KjR4=9MD  
1. 创建Matlab服务器。 hFb fNB3  
2. 移动探测面对于前一聚焦面的位置。 'wQy]zm$  
3. 在探测面追迹光线 mc@M,2@D  
4. 在探测面计算照度 [Z}B"  
5. 使用PutWorkspaceData发送照度数据到Matlab a>Re^GT+z  
6. 使用PutFullMatrix发送标量场数据到Matlab中 z&'f/w8  
7. 用Matlab画出照度数据 wa3F  
8. 在Matlab计算照度平均值 F,Fo}YQX  
9. 返回数据到FRED中 6&!l'[hU
