[推荐]FRED案例-FRED如何调用Matlab [复制链接]

"dX~J3$  
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。 r6Yd"~

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： 6+IhI?lI=  
enableservice('AutomationServer', true) id1cZig  
    enableservice('AutomationServer') S@HC$  
TjTG+uQ  
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。 ='o3<}

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： f47]gtB-  
1. 在FRED脚本编辑界面找到参考. Q:(mK* _  
2. 找到Matlab Automation Server Type Library )OV0YfO  
    3. 将名字改为MLAPP KUUA>'=

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。 \dtiv&x

3. 在探测面追迹光线 ^~YT<cJ1h  
4. 在探测面计算照度 o%t4WQ|bj
