    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。 /b|0PMX  
    ;gC|  
    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: +a^F\8H  
    enableservice('AutomationServer', true) L@JOGCYy  
    enableservice('AutomationServer') tGB@$UmfU  
    9n}p;3{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 Xl74@wq   
    Vf(6!iRP@  
    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: !x'/9^i~v  
    1. 在FRED脚本编辑界面找到参考. PqM1a oyX  
    2. 找到Matlab Automation Server Type Library tpuYiL  
    3. 将名字改为MLAPP u.rY#cS,-R

    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。 >vo=]c w

    现在将脚本代码公布如下,此脚本执行如下几个步骤: v9T_&  
    1. 创建Matlab服务器。 'U'yC2BI n  
    2. 移动探测面对于前一聚焦面的位置。 }^B6yWUN  
    3. 在探测面追迹光线 OT&k.!=  
    4. 在探测面计算照度 wj[$9UJb  
    5. 使用PutWorkspaceData发送照度数据到Matlab Rb3V^;i  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 )?wJF<[_#  
    7. 用Matlab画出照度数据 1yqJwy;X  
    8. 在Matlab计算照度平均值 WOh|U4vt  
    9. 返回数据到FRED中 &HSq(te
