    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。 YH&bD16c3  
    jh2t9SI~  
    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: 3psU?8(  
    enableservice('AutomationServer', true) 29CINC  
    enableservice('AutomationServer') 91>fqe  
    fjk\L\1  
    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 :+Om]#`Vls  
    kVK/9dy-F  
    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: ^j#rZ;uc   
    1. 在FRED脚本编辑界面找到参考. B33$pUk  
    2. 找到Matlab Automation Server Type Library &F STpBu  
    3. 将名字改为MLAPP #jA[9gWI  
    c:Wze*vI ;  
    o*U]v   
    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。 B(xN Gs

    现在将脚本代码公布如下,此脚本执行如下几个步骤: EF3Cdu{]P  
    1. 创建Matlab服务器。 b)(?qfXWP  
    2. 移动探测面对于前一聚焦面的位置。 !*6CWV0  
    3. 在探测面追迹光线 7qTE('zt  
    4. 在探测面计算照度 L|bwZ,M=}?  
    5. 使用PutWorkspaceData发送照度数据到Matlab r{l(O,|e  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 .`>y@p!  
    7. 用Matlab画出照度数据 jReXyRmo({

    9. 返回数据到FRED中 ( =~&+z
