    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。 Tc>g+eS  
    tNOOaj9mw  
    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: W>c*\)Xk !  
    enableservice('AutomationServer', true) u-bgk(u  
    enableservice('AutomationServer') :/Z1$xS  
    Fo5UG2E&  
    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 #,FXc~V  
    &oJ[ *pQ  
    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:  BPKrRex  
    1. 在FRED脚本编辑界面找到参考. D5xTuv9T  
    2. 找到Matlab Automation Server Type Library \{Je!#  
    3. 将名字改为MLAPP /xr75|-8  
    P1]F0fR  
    mq(K_  
    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。 ZEpu5`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: P]2 /}\f  
    1. 创建Matlab服务器。 Cv&>:k0V  
    2. 移动探测面对于前一聚焦面的位置。 `r}a:w-  
    3. 在探测面追迹光线 hv#LKyp%  
    4. 在探测面计算照度 vS:=%@c>ta  
    5. 使用PutWorkspaceData发送照度数据到Matlab qC=ZH#  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 e(OKE7  
    7. 用Matlab画出照度数据 uKJo5%>  
    8. 在Matlab计算照度平均值 1gvh6eE F  
    9. 返回数据到FRED中 !:uh? RW
