    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。 6^%UU o%  
    vK 7^*qr;j  
    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: / rg*p  
    enableservice('AutomationServer', true) _Bj)r}~7#  
    enableservice('AutomationServer') +IrLDsd  
    0="%Y ^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 r9X?PA0f  
    jL(qf~c_  
    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: 9w"h  
    1. 在FRED脚本编辑界面找到参考. wyp|qIS;  
    2. 找到Matlab Automation Server Type Library ;ToKJ6hN|*  
    3. 将名字改为MLAPP =NOH:#iQ  
    :r%P.60H X  
    Nqw&< x+  
    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。 9!T[Z/}T

    现在将脚本代码公布如下,此脚本执行如下几个步骤: kdCUORMK  
    1. 创建Matlab服务器。 %TX@I$Ba  
    2. 移动探测面对于前一聚焦面的位置。 =jSb'Vu|  
    3. 在探测面追迹光线 =.y~fA!  
    4. 在探测面计算照度 ZPiq-q  
    5. 使用PutWorkspaceData发送照度数据到Matlab :q=%1~Idla  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 +lJG(Qd  
    7. 用Matlab画出照度数据 }Mo=PWI1?  
    8. 在Matlab计算照度平均值 7.C;NT  
    9. 返回数据到FRED中 3mYiQ2
