FRED如何调用Matlab

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。 a8bX"#OR&N  
W;OYO  
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: {hs2?#p  
enableservice('AutomationServer', true) K'iS#i7  
enableservice('AutomationServer')  \]f5  
P;L)1 g  
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。 +Dq|l}

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: r{R[[]p  
1. 在FRED脚本编辑界面找到参考. k lP{yxU'n  
2. 找到Matlab Automation Server Type Library oN&rq6eN  
3. 将名字改为MLAPP vu_>U({. T

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。 u n?j

现在将脚本代码公布如下,此脚本执行如下几个步骤: Pg*?[^*  
1. 创建Matlab服务器。 tAb;/tM3I  
2. 移动探测面对于前一聚焦面的位置。 B&%L`v2[  
3. 在探测面追迹光线 36kc4=  
4. 在探测面计算照度 =1{H Sf  
5. 使用PutWorkspaceData发送照度数据到Matlab ,-cpsN  
6. 使用PutFullMatrix发送标量场数据到Matlab中 |MOn0 *  
7. 用Matlab画出照度数据 gD,YQ%aq  
8. 在Matlab计算照度平均值 v{mv*`~nA\  
9. 返回数据到FRED中 kz7vbY
