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。 T_gW't>   
VNytK_F0P  
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:  R6AZIN:  
enableservice('AutomationServer', true) ,[ Ytl  
enableservice('AutomationServer') ;wvV hQ  
p(x[zn+%Y  
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。 pCg0xbc`

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: zxsnrn;|  
1. 在FRED脚本编辑界面找到参考. f'%}{l: ss  
2. 找到Matlab Automation Server Type Library ;2X1qw>  
3. 将名字改为MLAPP t~bjDV^`

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。 beIEy(rA

现在将脚本代码公布如下,此脚本执行如下几个步骤: EIf~>AI  
1. 创建Matlab服务器。 "+HZ~:~f  
2. 移动探测面对于前一聚焦面的位置。 )T2Sw z/  
3. 在探测面追迹光线 (oTx*GP>Y  
4. 在探测面计算照度 ^Nc\D7( l  
5. 使用PutWorkspaceData发送照度数据到Matlab _|s{G  
6. 使用PutFullMatrix发送标量场数据到Matlab中 i-/'F  
7. 用Matlab画出照度数据 L:%h]-  
8. 在Matlab计算照度平均值 Mv ;7kC7]  
9. 返回数据到FRED中 pWQ?pTh
