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。 ^GMM%   
:%-xiv  
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: w ryjs!  
enableservice('AutomationServer', true) I,J*\)-%J  
enableservice('AutomationServer') oRmz'F  
OE_;i}58  
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。 qXC>D Gy

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: d/oxRzk'L  
1. 在FRED脚本编辑界面找到参考. aF2vw{wT}  
2. 找到Matlab Automation Server Type Library 7`AQn],  
3. 将名字改为MLAPP gbF^m`A>%+  
O%feBe  
MD`1KC_m  
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。 >~C*m `#

现在将脚本代码公布如下,此脚本执行如下几个步骤: hI249gW9  
1. 创建Matlab服务器。 B^Z %38o  
2. 移动探测面对于前一聚焦面的位置。 :2^j/  
3. 在探测面追迹光线 p1^k4G  
4. 在探测面计算照度 o9&&u1`M/  
5. 使用PutWorkspaceData发送照度数据到Matlab <*I%U]  
6. 使用PutFullMatrix发送标量场数据到Matlab中 6XU1w  
7. 用Matlab画出照度数据 ]7W !  
8. 在Matlab计算照度平均值 CF"u8yE  
9. 返回数据到FRED中 VsLlPw{
