    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。 J\9jsx!WQ  
    ROcY'-  
    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: m}sh I8S  
    enableservice('AutomationServer', true) g!z8oPT  
    enableservice('AutomationServer') FxMMxY,*%  
    Z7ZWf'o  
    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 zbdOCfA;

    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: A Z]Z,s6  
    1. 在FRED脚本编辑界面找到参考. 1j8/4:  
    2. 找到Matlab Automation Server Type Library ~p0 e=u  
    3. 将名字改为MLAPP t/_\U =i$

    hlt9x.e.A  
    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。 s"gKonwI2

    现在将脚本代码公布如下,此脚本执行如下几个步骤: =/)Mc@Hb  
    1. 创建Matlab服务器。 zV9 =  
    2. 移动探测面对于前一聚焦面的位置。 YeR7*[l  
    3. 在探测面追迹光线 Iht mD@H}  
    4. 在探测面计算照度 _ +u sn.  
    5. 使用PutWorkspaceData发送照度数据到Matlab t>fA!K%{  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 })Ix .!p  
    7. 用Matlab画出照度数据 xUV_2n+  
    8. 在Matlab计算照度平均值 $,!dan<eA  
    9. 返回数据到FRED中 KI^q 5D ?
