    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。 [IF5Iv\b  
    6%hr]>L  
    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: m0I)_R#X[  
    enableservice('AutomationServer', true) X7cqAi  
    enableservice('AutomationServer') m zh8<w?ns  
    )O xsasn)M  
    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 =i4%KF9 x

    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: cN#c25S>  
    1. 在FRED脚本编辑界面找到参考. jvI!BZ  
    2. 找到Matlab Automation Server Type Library C#^V<:9  
    3. 将名字改为MLAPP ^ZxT0oaL

    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。 xppl6v(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: fEdp^oVg  
    1. 创建Matlab服务器。 ~o_zV'^f@o  
    2. 移动探测面对于前一聚焦面的位置。 X]Aobtz  
    3. 在探测面追迹光线 =bx;TV  
    4. 在探测面计算照度 #-]!;sY>  
    5. 使用PutWorkspaceData发送照度数据到Matlab F9Hxqa#1T  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 FO"sE`  
    7. 用Matlab画出照度数据 N;YAG#'9~_  
    8. 在Matlab计算照度平均值 Y#VtZTcT
