[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。 E'iN==p_:  
HS@ EV iht  
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： 4T??8J-J  
enableservice('AutomationServer', true) ~Iz{@Ep*  
enableservice('AutomationServer') VBq|j"o0"  
Em]2K:  
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。 EC`=nGF

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： !lxq,Whr{  
1. 在FRED脚本编辑界面找到参考. p6AF16*f0  
2. 找到Matlab Automation Server Type Library >`=9So_J  
3. 将名字改为MLAPP y"T(Unvc

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。 +aZcA#%

现在将脚本代码公布如下，此脚本执行如下几个步骤： KbGz3O'u  
1. 创建Matlab服务器。 OVUJiBp  
2. 移动探测面对于前一聚焦面的位置。 ;km^ OO$  
3. 在探测面追迹光线 sL4j@Lt  
4. 在探测面计算照度 _@@.VmZL  
5. 使用PutWorkspaceData发送照度数据到Matlab l>*L Am5  
6. 使用PutFullMatrix发送标量场数据到Matlab中 _~.S~;o!b  
7. 用Matlab画出照度数据 3Q!)bMv \  
8. 在Matlab计算照度平均值 Id^)WEK4  
9. 返回数据到FRED中 aL^ 58My&
