    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。 FJW`$5?  
    !}y8S'Yjw  
    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  
    enableservice('AutomationServer', true) Ty.drM  
    enableservice('AutomationServer') ~ J%m  
    Xa>}4j.  
    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 }0vtc[!  
    a~6ztEhGm  
    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: H8( C>w-'  
    1. 在FRED脚本编辑界面找到参考. y. T ct.  
    2. 找到Matlab Automation Server Type Library I51M}b,[d  
    3. 将名字改为MLAPP sBbL~ce50?

    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。 =[APMig,n

    3. 在探测面追迹光线 O~nBz):2  
    4. 在探测面计算照度 Z"4VH rA  
    5. 使用PutWorkspaceData发送照度数据到Matlab m)(SG  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ]<Z&=0i#9  
    7. 用Matlab画出照度数据 8xc8L1;
