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。 Jqxd92 bI  
9`f@"%h  
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: 9Q9{>d#"  
enableservice('AutomationServer', true) ?'k_K:_  
enableservice('AutomationServer') YoKE=ln7  
6{)pF  
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。 do8[wej<:  
$@Vn+| Ix  
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: `rn/H;r!Z  
1. 在FRED脚本编辑界面找到参考. l= {Y[T&  
2. 找到Matlab Automation Server Type Library hV@ N -u^  
3. 将名字改为MLAPP ?M:>2wl

UBL{3s^"  
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。 lAnq2j|

现在将脚本代码公布如下,此脚本执行如下几个步骤: /si<Fp)z  
1. 创建Matlab服务器。 W`x.qumN  
2. 移动探测面对于前一聚焦面的位置。 1m5l((d  
3. 在探测面追迹光线 jRg/N_2'2  
4. 在探测面计算照度 WaB0?jI  
5. 使用PutWorkspaceData发送照度数据到Matlab y[b 8rv  
6. 使用PutFullMatrix发送标量场数据到Matlab中 1'f_C<.0  
7. 用Matlab画出照度数据 z|Y54o3  
8. 在Matlab计算照度平均值 ;a?<7LIx  
9. 返回数据到FRED中 CU|E-XPW
