[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。 zBTyRL l  
&;]KntxB  
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： Q,m1mIf  
enableservice('AutomationServer', true) ruQ1Cph  
enableservice('AutomationServer') j!<(`  
(Ld,<!eN0  
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。

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： aBonq]W  
1. 在FRED脚本编辑界面找到参考. sV`!4 u7%}  
2. 找到Matlab Automation Server Type Library u#"L gG.X  
3. 将名字改为MLAPP 85GU~.

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。 78fFAN`

现在将脚本代码公布如下，此脚本执行如下几个步骤： u?B9zt%$-m  
1. 创建Matlab服务器。 +<1MY'>y  
2. 移动探测面对于前一聚焦面的位置。 1ms(03dp  
3. 在探测面追迹光线 r(VznKSx  
4. 在探测面计算照度 |`,AAa  
5. 使用PutWorkspaceData发送照度数据到Matlab +zf[Im%E  
6. 使用PutFullMatrix发送标量场数据到Matlab中 g`9`/  
7. 用Matlab画出照度数据 he\

8. 在Matlab计算照度平均值 p.|NZXk%%a  
9. 返回数据到FRED中 rZSD)I
