    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。 ZT d)4f  
    U'oFW@Y;h  
    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: ~bnyk%S o  
    enableservice('AutomationServer', true) Gzw9E.Hk  
    enableservice('AutomationServer') `iZ){JfAH  
    y{k65dk-  
    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 6cVJu%<V  
    G 5!J9@Yi  
    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: 'Z}3XVZEN  
    1. 在FRED脚本编辑界面找到参考. \NF5)]:  
    2. 找到Matlab Automation Server Type Library Ej#pM.  
    3. 将名字改为MLAPP 'jA>P\@8  
     c_ Dg0  
    < pWk   
    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。 <nk7vo?Ks

    现在将脚本代码公布如下,此脚本执行如下几个步骤: CBKLct>  
    1. 创建Matlab服务器。 N?j#=b+D  
    2. 移动探测面对于前一聚焦面的位置。 B }t529Z  
    3. 在探测面追迹光线 5i1E 5@~  
    4. 在探测面计算照度 jzb%?8ZJ  
    5. 使用PutWorkspaceData发送照度数据到Matlab g/(3D  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ={G0p=~+,p  
    7. 用Matlab画出照度数据 ,ui=Wi1  
    8. 在Matlab计算照度平均值 MG-#p8  
    9. 返回数据到FRED中 !L3\B_#
