[推荐]FRED案例-FRED如何调用Matlab [复制链接]

zPZy#7/A  
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。 gy,B+~p  
yG{'hx6H  
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： iw<+rh*C  
enableservice('AutomationServer', true) ?;!l-Dy  
    enableservice('AutomationServer') ga0W;Vq&X  
0t'WM=W<!8  
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。 enE8T3

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： 8+Oyhd*|  
1. 在FRED脚本编辑界面找到参考. e*=N\$  
2. 找到Matlab Automation Server Type Library  pb6z)8  
    3. 将名字改为MLAPP ?tg(X[h{S

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。 $D<LND=o=

现在将脚本代码公布如下，此脚本执行如下几个步骤： Sycs u_je  
1. 创建Matlab服务器。 Z[[@O  
2. 移动探测面对于前一聚焦面的位置。 r^q@rL>   
3. 在探测面追迹光线 [C.Pzo  
4. 在探测面计算照度 Z<;am  
5. 使用PutWorkspaceData发送照度数据到Matlab l0l2fwz(  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Si.3Je[q  
7. 用Matlab画出照度数据 &FW|O(

8. 在Matlab计算照度平均值 R=_ fk  
9. 返回数据到FRED中 wk'|gI[W
