    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。 6hs2B5)+  
    (SlrV8;  
    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: bUp ,vc*  
    enableservice('AutomationServer', true) &G>EBKn\2`  
    enableservice('AutomationServer') @BZ6{@*  
    cn4C K. ?  
    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 OgTE^W@  
    vZns,K#4H\  
    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: g(0 |p6R  
    1. 在FRED脚本编辑界面找到参考. -\`n{$OR  
    2. 找到Matlab Automation Server Type Library zaVDe9B,7  
    3. 将名字改为MLAPP sgn,]3AUq  
    U&mJ_f#M  
    +{j? +4(B  
    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。 ZTx~+'(

    3. 在探测面追迹光线 F%Lniv/N  
    4. 在探测面计算照度 o 2 5kFD  
    5. 使用PutWorkspaceData发送照度数据到Matlab e_wz8]K)n  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 xi=qap=S^9  
    7. 用Matlab画出照度数据 C'hI{4@P
