[分享]FRED如何调用Matlab [复制链接]

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。 w(aj'i  
97\K]Tr  
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： {*F =&D  
enableservice('AutomationServer', true) TP {\V>*Yz  
enableservice('AutomationServer') K$,<<hl  
J&fIWZ  
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。 #}B1W&\sw

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： 0$c(<+D  
1. 在FRED脚本编辑界面找到参考. A03io8D6  
2. 找到Matlab Automation Server Type Library <!FcQVH+L  
3. 将名字改为MLAPP (wq8[1Wzup

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。 f4\$<g/~

现在将脚本代码公布如下，此脚本执行如下几个步骤： T=u"y;&L  
1. 创建Matlab服务器。 ?xH{7)dO  
2. 移动探测面对于前一聚焦面的位置。 4V

3. 在探测面追迹光线 2"Wq

4. 在探测面计算照度 (?8i^T?WP=  
5. 使用PutWorkspaceData发送照度数据到Matlab vJGH8$%;,  
6. 使用PutFullMatrix发送标量场数据到Matlab中 4]m{^z`1  
7. 用Matlab画出照度数据 n0co* ]X+k  
8. 在Matlab计算照度平均值 BK4S$B  
9. 返回数据到FRED中 z"yW):X
