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。 u6iU[5  
?x5wS$^q<  
配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: !Ig|m+  
enableservice('AutomationServer', true) ,N@Yk.  
enableservice('AutomationServer') 8z."X$  
#90[PASx  
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。 *%OYAsc

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: DD/>{kff  
1. 在FRED脚本编辑界面找到参考. "W &:j:o  
2. 找到Matlab Automation Server Type Library |b$>68:  
3. 将名字改为MLAPP WNn[L=f

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。 E'e8&3!bx

现在将脚本代码公布如下,此脚本执行如下几个步骤: z.2r@Psk  
1. 创建Matlab服务器。 %1-K);S J  
2. 移动探测面对于前一聚焦面的位置。 V-KL%  
3. 在探测面追迹光线 nabBU4;h  
4. 在探测面计算照度 GSMk\9SI  
5. 使用PutWorkspaceData发送照度数据到Matlab ;ZQ- uz  
6. 使用PutFullMatrix发送标量场数据到Matlab中 KA5~">l  
7. 用Matlab画出照度数据 :]CzN^k(1c  
8. 在Matlab计算照度平均值 *#&k+{a^2  
9. 返回数据到FRED中 X q}Ucpj
