    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。 ,xIWyI.  
    qXQ7Jg9  
    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: #)$@Kvm  
    enableservice('AutomationServer', true) TWJ%? /d  
        enableservice('AutomationServer') Yc1ve  
    !4 G9`>n  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 XDq*nA8#5B  
    /bv4/P  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ]+i~Cbj  
    1. 在FRED脚本编辑界面找到参考. hlTM<E  
    2. 找到Matlab Automation Server Type Library FG5t\!dt<  
        3. 将名字改为MLAPP EXYr_$gRs  
         (SYSw%v$A  
         'x!5fAy  
    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。 k M' :.QT

    现在将脚本代码公布如下,此脚本执行如下几个步骤: K ZSvT{  
    1. 创建Matlab服务器。 sYb(g'W*'  
    2. 移动探测面对于前一聚焦面的位置。 Kdwt^8Umh  
    3. 在探测面追迹光线 B>M@'  
    4. 在探测面计算照度 -V)DKf"f  
    5. 使用PutWorkspaceData发送照度数据到Matlab Q'S"$^~{  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 {z/Y~rf  
    7. 用Matlab画出照度数据  ,L}  
    8. 在Matlab计算照度平均值 K0O&-v0"1  
    9. 返回数据到FRED中 Ljjuf=]
