    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。 tGjhHp8}c  
    29&bbfU  
    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: d%_OT0Ei  
    enableservice('AutomationServer', true) _,haD)1g~  
    enableservice('AutomationServer') (UL4+ta  
    [;A[.&6  
    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 *bd[S0l  
    X6\ sF"E  
    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: TP%+.#Fu  
    1. 在FRED脚本编辑界面找到参考. "ZrOrdlg+A  
    2. 找到Matlab Automation Server Type Library ^v&D;<&R  
    3. 将名字改为MLAPP i#/]KsSp  
    s58 C2  
    t `kui.  
    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。 {pL+2%`~

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :9|\Z|S(I  
    1. 创建Matlab服务器。 rHjq1-t  
    2. 移动探测面对于前一聚焦面的位置。 v&a4^s  
    3. 在探测面追迹光线 *=AqM14 @  
    4. 在探测面计算照度 >w+HHs/$wK  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,m_WR7!$E  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8NBT|N~N  
    7. 用Matlab画出照度数据 zCv"]%  
    8. 在Matlab计算照度平均值 S35~Cp  
    9. 返回数据到FRED中 \xv;sl$f
