    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。 &B) F_EI  
    9:P)@UF  
    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: cu Nwv(P  
    enableservice('AutomationServer', true) } nQHP4'  
    enableservice('AutomationServer') 6A%Y/oU+2  
    .EI/0"^  
    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 $T1c{T6n}  
    Th-zMQ4  
    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: ;m\E9ple  
    1. 在FRED脚本编辑界面找到参考. {r Gx*<e  
    2. 找到Matlab Automation Server Type Library (bXCc  
    3. 将名字改为MLAPP 5ewQjwW0

    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。 k|w6&k3

    3. 在探测面追迹光线 7m1*Q@D

    5. 使用PutWorkspaceData发送照度数据到Matlab \"n&|_SZ\  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 nHA2p`T  
    7. 用Matlab画出照度数据 }=wSfr9g
