    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。 NPK;  
    zMv`<m%  
    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: Y~vk>ZC  
    enableservice('AutomationServer', true) I=kqkuW  
    enableservice('AutomationServer') p AOKy  
    w a_{\v=  
    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 KnkmGy  
    ,`bW (V  
    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: f'oTN!5WF  
    1. 在FRED脚本编辑界面找到参考. MJ JC6:  
    2. 找到Matlab Automation Server Type Library ~6f/jCluR%  
    3. 将名字改为MLAPP _d]{[& p4t  
    -TF},V~  
    ESCN/ocV  
    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。 gy}3ZA*F

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 28"1ONs 3  
    1. 创建Matlab服务器。 f6Y?),`  
    2. 移动探测面对于前一聚焦面的位置。 @rYZ0`E9  
    3. 在探测面追迹光线 M2Nh3ijr  
    4. 在探测面计算照度 GrLxERf  
    5. 使用PutWorkspaceData发送照度数据到Matlab jlBsm'M<m  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @@D/&}#F  
    7. 用Matlab画出照度数据 E{T3Xwg  
    8. 在Matlab计算照度平均值 zIF1A*UH  
    9. 返回数据到FRED中 Xex7Lr&
