[技术]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。 2mO#vTX4  
JA}'d7yEa  
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： hK"=~\,  
enableservice('AutomationServer', true) jysV%q 3  
enableservice('AutomationServer') [0LqZ<\5  
aC},h  
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。 h=tu+pn  
c-T ^ aR  
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： AN>`M?EQ  
1. 在FRED脚本编辑界面找到参考. P~<93  
2. 找到Matlab Automation Server Type Library CJOl|"UyJ  
3. 将名字改为MLAPP ##_Za6/n

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。 *\WI!%

现在将脚本代码公布如下，此脚本执行如下几个步骤： "k|`xn  
1. 创建Matlab服务器。 h6e$$-_  
2. 移动探测面对于前一聚焦面的位置。 $te,\$&}  
3. 在探测面追迹光线 EAB+kY  
4. 在探测面计算照度 lnWiE}F  
5. 使用PutWorkspaceData发送照度数据到Matlab F"H!CJ

6. 使用PutFullMatrix发送标量场数据到Matlab中 w2+]C&B*  
7. 用Matlab画出照度数据 aTm.10{^  
8. 在Matlab计算照度平均值 j*u9+.   
9. 返回数据到FRED中 W~F/ZrT3A
