    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。 ff}a <w  
    d[]p_oIQq  
    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: f3TlJ!!U  
    enableservice('AutomationServer', true) Lkl|4L   
    enableservice('AutomationServer') ^~6]0$yJ  
    `<}V !Lo  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 ?S&w0}R  
    U7"BlT!V\  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: @\T;PTD-  
    1. 在FRED脚本编辑界面找到参考. J/x@$'  
    2. 找到Matlab Automation Server Type Library HD:%Yv  
    3. 将名字改为MLAPP 3K#mF7)a  
    zzfn0g  
    t+ S~u^  
    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。 _+*/~E

    现在将脚本代码公布如下,此脚本执行如下几个步骤: &=-e`=qJ'6

    3. 在探测面追迹光线 v<%kd[N  
    4. 在探测面计算照度 MxgLzt Y  
    5. 使用PutWorkspaceData发送照度数据到Matlab lkg"'p{  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [X }@Ct6  
    7. 用Matlab画出照度数据 f#v#)Gp+  
    8. 在Matlab计算照度平均值 $Pd|6  
    9. 返回数据到FRED中 G*(K UG>
