    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。 z[Xs=S!]I  
    v?BX 4FO  
    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: GhpVi<FL  
    enableservice('AutomationServer', true) /=&HunaxI  
    enableservice('AutomationServer') W- 5Z"m1I  
    K n%[&  
    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 [t/7hx"2t  
    ts/ rV#s~  
    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: 'bVDmm).  
    1. 在FRED脚本编辑界面找到参考.  "_t2R &A  
    2. 找到Matlab Automation Server Type Library 8gWifx #N  
    3. 将名字改为MLAPP b!Pz~faXD  
    *m6~x-x  
    <|9s {z  
    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。 oe`t ? (U

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 'z7,)Q&8  
    1. 创建Matlab服务器。 ew -5VL

    3. 在探测面追迹光线 XA75tU[#  
    4. 在探测面计算照度 ]`39E"zY  
    5. 使用PutWorkspaceData发送照度数据到Matlab |2w,Np-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ;zVtJG`  
    7. 用Matlab画出照度数据 'oSs5lW  
    8. 在Matlab计算照度平均值 ~/s(.oji  
    9. 返回数据到FRED中 DU(QQ53
