[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。 29z@ !  
#T>pu/EQX_  
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： xyV7MW\?w  
enableservice('AutomationServer', true) (s+}l?  
enableservice('AutomationServer') ),,0T/69+9  
~1Ffu 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。 sVlQ5M oo(

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： on7?V<  
1. 在FRED脚本编辑界面找到参考. F)aF.'$-/  
2. 找到Matlab Automation Server Type Library 'v(b^x<ZS  
3. 将名字改为MLAPP aMK\&yZD  
A0ZU
#"'/  
Yru,YA   
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。 f(EO|d^u

现在将脚本代码公布如下，此脚本执行如下几个步骤： T0o0_R  
1. 创建Matlab服务器。 <pFbm  
2. 移动探测面对于前一聚焦面的位置。 YvUV9qps~  
3. 在探测面追迹光线 R2Q1Rk#  
4. 在探测面计算照度 MbQ%'z6D  
5. 使用PutWorkspaceData发送照度数据到Matlab &jr

6. 使用PutFullMatrix发送标量场数据到Matlab中 ziQ&M\  
7. 用Matlab画出照度数据 @6y)wA9Yx  
8. 在Matlab计算照度平均值 >+%0|

9. 返回数据到FRED中 Vc8w[oS
