    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。 yi<H }&  
    @f#6Nu  
    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: EiPOY'  
    enableservice('AutomationServer', true) .aC/ g?U  
    enableservice('AutomationServer') 4SIS #m  
    8&y#LeM1TT  
    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 F ^)( 7}ph  
    gZL,xX  
    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: 5QG?*Z~?7  
    1. 在FRED脚本编辑界面找到参考. =pb ru=/  
    2. 找到Matlab Automation Server Type Library SM.KM_%K  
    3. 将名字改为MLAPP }n k [WW  
    N1JM[<PP  
    qKI)*o062  
    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。 'Z6x\p

    现在将脚本代码公布如下,此脚本执行如下几个步骤: kq> I?wg  
    1. 创建Matlab服务器。 \| 'Yuh  
    2. 移动探测面对于前一聚焦面的位置。 Hw,@oOh.  
    3. 在探测面追迹光线 oUL4l=dj.  
    4. 在探测面计算照度 To,*H OP  
    5. 使用PutWorkspaceData发送照度数据到Matlab R-Gg= l5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 YN7JJJ/~T  
    7. 用Matlab画出照度数据 ~Vf A  
    8. 在Matlab计算照度平均值 |0VZ1{=*  
    9. 返回数据到FRED中 $AdBX}{
