[推荐]FRED案例-FRED如何调用Matlab [复制链接]

<!&&Qd-d6H  
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。 4.7ePbk[E  
S@zsPzw  
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： gydPy
*  
enableservice('AutomationServer', true) PKu+$  
    enableservice('AutomationServer') UR?[ba_h  
)[6H!y
5  
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。 8p7Uvn+m*

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： oa+Rr&t'  
1. 在FRED脚本编辑界面找到参考. W\zg#5fmK  
2. 找到Matlab Automation Server Type Library -ny[Lh^b  
    3. 将名字改为MLAPP =_8

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。 j%b/1@I

现在将脚本代码公布如下，此脚本执行如下几个步骤： ow ~(k5k:  
1. 创建Matlab服务器。 F`U%xn,  
2. 移动探测面对于前一聚焦面的位置。 ^l ~i>:V  
3. 在探测面追迹光线 R1X9  
4. 在探测面计算照度 f>5{SoM  
5. 使用PutWorkspaceData发送照度数据到Matlab 1Af~6jz  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 j"/i+r{"E  
7. 用Matlab画出照度数据 _5.^A&Y*  
8. 在Matlab计算照度平均值 [a

9. 返回数据到FRED中 Xf9<kbRw/
