[推荐]FRED案例-FRED如何调用Matlab [复制链接]

S4'  
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,rlrxI  
xC{qV,  
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： : ]sUpO  
enableservice('AutomationServer', true) 8"U. Hnu  
    enableservice('AutomationServer') Gcdd3W`O  
b6Wqr/  
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。 7uKNd *%

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： 2^y^q2(r  
1. 在FRED脚本编辑界面找到参考. \
!k1a^ZP  
2. 找到Matlab Automation Server Type Library ex::m&  
    3. 将名字改为MLAPP

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。 /JHc!D

现在将脚本代码公布如下，此脚本执行如下几个步骤： m;'6MHx;  
1. 创建Matlab服务器。 t; 4]cg:_  
2. 移动探测面对于前一聚焦面的位置。 8vMG5

3. 在探测面追迹光线 gu0j.XS^  
4. 在探测面计算照度 =h0,?]z  
5. 使用PutWorkspaceData发送照度数据到Matlab n;@bLJ$W  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?\t#1"d  
7. 用Matlab画出照度数据 pimtiQqC  
8. 在Matlab计算照度平均值 yKa{08X:  
9. 返回数据到FRED中 Fx;QU)1l3
