    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。 5c}loOq  
    p>J@"?%^  
    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: (U$;0`  
    enableservice('AutomationServer', true) 2 #yDVN$  
    enableservice('AutomationServer') /DHV-L  
    P"}"q ![  
    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 C7W<7DBf

    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: wE<r'  
    1. 在FRED脚本编辑界面找到参考. P~lU`.X}  
    2. 找到Matlab Automation Server Type Library Yc6.v8a  
    3. 将名字改为MLAPP 7Q Ns q

    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。 9a+Y )?z

    3. 在探测面追迹光线 "Vl4=W)u  
    4. 在探测面计算照度 noz1W ]  
    5. 使用PutWorkspaceData发送照度数据到Matlab w8$> 2  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ! N!pvK;  
    7. 用Matlab画出照度数据 .)bNi*&  
    8. 在Matlab计算照度平均值 .w{Y3,dd>
