[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。 x,=&JtKVc  
;km`P|
<U  
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： Bd!bg|uO*  
enableservice('AutomationServer', true) QyEnpZ8?a  
enableservice('AutomationServer') /C:Y94B-z  
v,FU
^f-'  
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。 8}I$'x

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： [;n9:Qxf  
1. 在FRED脚本编辑界面找到参考. MU`1LHg  
2. 找到Matlab Automation Server Type Library R{C(K(5/  
3. 将名字改为MLAPP k0OYJ/

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。 L O}@dL

现在将脚本代码公布如下，此脚本执行如下几个步骤： T;Lka

1. 创建Matlab服务器。 0!4Ts3qn1  
2. 移动探测面对于前一聚焦面的位置。 H`*LBqDk  
3. 在探测面追迹光线 3atBX5  
4. 在探测面计算照度 D#_3^Kiawj  
5. 使用PutWorkspaceData发送照度数据到Matlab 5#HW2"7  
6. 使用PutFullMatrix发送标量场数据到Matlab中 "IZa!eUW  
7. 用Matlab画出照度数据 xs{3pkTYD  
8. 在Matlab计算照度平均值 !S$:*5=&  
9. 返回数据到FRED中 NxkGOAOE
