[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。 NA8$G|.?  
SE!0f&  
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： Z0%Qy+%  
enableservice('AutomationServer', true) f9&po2Pzf  
enableservice('AutomationServer') {[.<BU-  
V\o&{7!  
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。 @460r

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： P"mD73a  
1. 在FRED脚本编辑界面找到参考. nqyB,vv0  
2. 找到Matlab Automation Server Type Library KF`@o@,  
3. 将名字改为MLAPP V2|XcR

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。

现在将脚本代码公布如下，此脚本执行如下几个步骤： <O?UC/$)7  
1. 创建Matlab服务器。 | sio:QP  
2. 移动探测面对于前一聚焦面的位置。 S+(-k0  
3. 在探测面追迹光线 7$* O+bkn:  
4. 在探测面计算照度 !G3d5d2)C  
5. 使用PutWorkspaceData发送照度数据到Matlab >w"k:O17  
6. 使用PutFullMatrix发送标量场数据到Matlab中 !,< )y}L^)  
7. 用Matlab画出照度数据 :|?nz$
