FRED如何调用Matlab

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。 o;I86dI6C  
jF85bb$  
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: Ps4A B#3  
enableservice('AutomationServer', true) lfd{O7L0b  
enableservice('AutomationServer') y N%Pe:R  
ED&KJnquWJ  
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。 RVy87_J1  
< _uv!N  
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: $& gidz/w  
1. 在FRED脚本编辑界面找到参考. v A~hkkj{  
2. 找到Matlab Automation Server Type Library o%Q2.  
3. 将名字改为MLAPP *9^k^h(r&4  
,{t!->K  
k5CIU}H"  
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。 5X|aa>/

现在将脚本代码公布如下,此脚本执行如下几个步骤: 3e1"5~?'<  
1. 创建Matlab服务器。 KO$8lMm$  
2. 移动探测面对于前一聚焦面的位置。 1uzfV)  
3. 在探测面追迹光线 e{S`iO  
4. 在探测面计算照度 ^E*C~;^S  
5. 使用PutWorkspaceData发送照度数据到Matlab ]2 N';(R  
6. 使用PutFullMatrix发送标量场数据到Matlab中 40/[ uW"  
7. 用Matlab画出照度数据 Yb/^Qk59  
8. 在Matlab计算照度平均值 ?"Q6;np*  
9. 返回数据到FRED中 '11hIu=:
