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。 ] #J ]f  
zPVA6~|l  
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: GEvif4  
enableservice('AutomationServer', true) 2[:`w),.  
enableservice('AutomationServer') _mn4z+  
V&f3>#n\  
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。 ~o8$/%Oeb/

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: 1Ju{IEV  
1. 在FRED脚本编辑界面找到参考. FB</~ g  
2. 找到Matlab Automation Server Type Library k r/[|.bq  
3. 将名字改为MLAPP fY6&PuDf.

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。 3W27R

现在将脚本代码公布如下,此脚本执行如下几个步骤: <ZnAPh  
1. 创建Matlab服务器。 [NuayO3  
2. 移动探测面对于前一聚焦面的位置。 ;=E3f^'s  
3. 在探测面追迹光线 ?=fJu\;  
4. 在探测面计算照度 PmTA3aH  
5. 使用PutWorkspaceData发送照度数据到Matlab "? R$9i  
6. 使用PutFullMatrix发送标量场数据到Matlab中 9x:c"S*  
7. 用Matlab画出照度数据 3 =S.-  
8. 在Matlab计算照度平均值 dpE+[O_  
9. 返回数据到FRED中 %i96@ 6O
