    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。 W[`ybGR<  
    IMdp"  
    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: C^'r>0  
    enableservice('AutomationServer', true) K\B!tk  
    enableservice('AutomationServer') !F~1+V>zP  
    s/J7z$NEU  
    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 (Dv GA I

    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: or;VmU8$zb  
    1. 在FRED脚本编辑界面找到参考. gU&+^e >  
    2. 找到Matlab Automation Server Type Library hTZ6@i/pS  
    3. 将名字改为MLAPP +&f_k@+  
    tGl|/

    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。 ZW"f*vwQo

    现在将脚本代码公布如下,此脚本执行如下几个步骤: H@zv-{}T8  
    1. 创建Matlab服务器。 S3U]AH)C  
    2. 移动探测面对于前一聚焦面的位置。 O{byMV{Ou  
    3. 在探测面追迹光线 \,p?pL<'  
    4. 在探测面计算照度 7u^wO<  
    5. 使用PutWorkspaceData发送照度数据到Matlab &``nD  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 2w1Mf<IXPo  
    7. 用Matlab画出照度数据 ?XyrG1('  
    8. 在Matlab计算照度平均值 B$s6|~
