[推荐]FRED案例-FRED如何调用Matlab [复制链接]

QJR},nZ3  
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。 asp\4-?$o  
/J!hKK^k  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： &A/b9GW^-  
enableservice('AutomationServer', true) Xf{p>-+DL  
    enableservice('AutomationServer') TI"Ki$jC  
> 9z-/e  
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。 +

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： ,1<6=vL  
1. 在FRED脚本编辑界面找到参考. 4-'0# a  
2. 找到Matlab Automation Server Type Library sMJa4P>O@  
    3. 将名字改为MLAPP 8/,s8u  
     mN R}%s  
     -\ew,y  
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。 *(i%\

1. 创建Matlab服务器。 !>K=@9NC|.  
2. 移动探测面对于前一聚焦面的位置。 t

3. 在探测面追迹光线 S4(?=,^-  
4. 在探测面计算照度 ~e){2_J&n  
5. 使用PutWorkspaceData发送照度数据到Matlab ^y|`\oyqwN  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 6B>*v`T:
