    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。 62;xK-U  
    ]@y%j'e  
    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: @GXKqi  
    enableservice('AutomationServer', true) {'alA  
    enableservice('AutomationServer') z,ryY'ua/I  
    I>rTqOK  
    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 ai d1eF  
    U=%(kOx  
    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: @?s>oSyV  
    1. 在FRED脚本编辑界面找到参考. x+~!M:fAc9  
    2. 找到Matlab Automation Server Type Library h [Sd3Z*  
    3. 将名字改为MLAPP V~jp

    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。 6yYjZ<

    现在将脚本代码公布如下,此脚本执行如下几个步骤: .~ uKr^%  
    1. 创建Matlab服务器。 D]>Z5nr |  
    2. 移动探测面对于前一聚焦面的位置。 S/*\j7cj  
    3. 在探测面追迹光线 IkmEctAU  
    4. 在探测面计算照度 E"[p_ALdC  
    5. 使用PutWorkspaceData发送照度数据到Matlab h}nS&.  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8wO4;  
    7. 用Matlab画出照度数据 b IxH0=f  
    8. 在Matlab计算照度平均值 7f3,czW  
    9. 返回数据到FRED中 ic}TiTK
