    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。 )rLMIk  
    l<(Y_PE:  
    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: %7`f{|.  
    enableservice('AutomationServer', true) drwgjLC+  
    enableservice('AutomationServer') ;d$qc<2uA  
    :ug4g6;#H0  
    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 1xf=_F0`&

    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: Cc?TSZ8[  
    1. 在FRED脚本编辑界面找到参考. *]JdHO  
    2. 找到Matlab Automation Server Type Library PN+G:Qv  
    3. 将名字改为MLAPP pS4&w8s

    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。 >Q,zNs

    现在将脚本代码公布如下,此脚本执行如下几个步骤: #sKWd  
    1. 创建Matlab服务器。 @+U,Nzd  
    2. 移动探测面对于前一聚焦面的位置。 ^5=UK7e5KY  
    3. 在探测面追迹光线 B@Nt`ky0*  
    4. 在探测面计算照度 zT~B 6  
    5. 使用PutWorkspaceData发送照度数据到Matlab o  A* G  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Vv$HR  
    7. 用Matlab画出照度数据 b4Y8N"hL%  
    8. 在Matlab计算照度平均值 Bqws!RM'&@  
    9. 返回数据到FRED中 k&hc m
