    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。 UcZ3v]$I  
    1JM~Ls%Z  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: .Qaqkb-Ty  
    enableservice('AutomationServer', true) 8LL);"$  
    enableservice('AutomationServer') '*pq@|q;t  
    lUrchLoDt  
    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 XjC+kH  
    )}R0'QGd  
    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: p`It=16trT  
    1. 在FRED脚本编辑界面找到参考. G100L}d"N  
    2. 找到Matlab Automation Server Type Library !tVV +vT#  
    3. 将名字改为MLAPP ~ rRIWfhb

    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。 ,J[sg7v cv

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Uc&0>_Z  
    1. 创建Matlab服务器。 CyE.q^Wm  
    2. 移动探测面对于前一聚焦面的位置。 .{6TX"M  
    3. 在探测面追迹光线 ?#W>^Za=  
    4. 在探测面计算照度 J[9jNCq|  
    5. 使用PutWorkspaceData发送照度数据到Matlab u5lj+?  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 g\ke,r6  
    7. 用Matlab画出照度数据 /];F4AO5  
    8. 在Matlab计算照度平均值 .w0?  
    9. 返回数据到FRED中 QF>H>=Za=
