    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。 ux3<l+jv^  
    ugx%_x6  
    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: 69NQ]{1  
    enableservice('AutomationServer', true) 7{qy7,Gp  
    enableservice('AutomationServer') .j>hI="b  
    C[Dav&=^F  
    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 x,S P'fcP  
    q^L<X)  
    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: B0WJ/)rK<  
    1. 在FRED脚本编辑界面找到参考. G\Ro}5TO  
    2. 找到Matlab Automation Server Type Library P7MeX(Tay  
    3. 将名字改为MLAPP ql?=(b;D  
    pL%r,Y_^\x  
    eT8}  
    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。 S"k *6 U

    1. 创建Matlab服务器。 ~JD nKo  
    2. 移动探测面对于前一聚焦面的位置。 Bk\Gj`"7  
    3. 在探测面追迹光线 &0(  
    4. 在探测面计算照度 FEW_bP/4  
    5. 使用PutWorkspaceData发送照度数据到Matlab TdGnf   
    6. 使用PutFullMatrix发送标量场数据到Matlab中 z)=+ F]  
    7. 用Matlab画出照度数据 01. &> Duw  
    8. 在Matlab计算照度平均值 u% n*gcY  
    9. 返回数据到FRED中 /?1nHBYPM
