    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。 IY!.j5q8  
    8f~*T  
    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: YsCY~e&  
    enableservice('AutomationServer', true) &'PLOyWw  
    enableservice('AutomationServer') ]YZ_kc^(V;  
    ZBU<L+#  
    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 Y@UW\d*'%I  
    rcLF:gd] 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: i,RbIZnJ  
    1. 在FRED脚本编辑界面找到参考. 01 +#2~S  
    2. 找到Matlab Automation Server Type Library BUi,+NdIk  
    3. 将名字改为MLAPP NODg_J~T  
    RJ4=AA|  
    @pJ;L1sn  
    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。 9ec#'i=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: SMB&sl  
    1. 创建Matlab服务器。 F|VHr@%  
    2. 移动探测面对于前一聚焦面的位置。 ZV5IZ&V!  
    3. 在探测面追迹光线 j)Q}5M  
    4. 在探测面计算照度 ,B x0  
    5. 使用PutWorkspaceData发送照度数据到Matlab X H!n{Of  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [<^'}-SJ  
    7. 用Matlab画出照度数据 l%i*.b(  
    8. 在Matlab计算照度平均值 SFP?ND+7  
    9. 返回数据到FRED中 QDK }e:4q
