    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。 <S12=<c?'  
    Q<yvpT(  
    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: 7Jpq7;  
    enableservice('AutomationServer', true) s%A?B 8,  
    enableservice('AutomationServer') n1b^o~agwC  
    cs[nFfM  
    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 Vw1  
    3ik~PgGoKQ  
    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: R_vK^Da  
    1. 在FRED脚本编辑界面找到参考. f?(g5o*2  
    2. 找到Matlab Automation Server Type Library zXkq2\GHA  
    3. 将名字改为MLAPP Ga pM~~

    s=Kz9WLy  
    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。 MOm+t]vq1

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Yqv!ZJ6  
    1. 创建Matlab服务器。 .Y }k@T40a  
    2. 移动探测面对于前一聚焦面的位置。 7 4hRG~  
    3. 在探测面追迹光线 cb/$P!j7  
    4. 在探测面计算照度 A[^k4 >  
    5. 使用PutWorkspaceData发送照度数据到Matlab X<f4X"y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 : z\||f  
    7. 用Matlab画出照度数据 H)Z$j&S{  
    8. 在Matlab计算照度平均值 m]}EVa_I`/  
    9. 返回数据到FRED中 7Oi<_b
