    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。 m+8:_0x "  
    /Z]nV2$n)V  
    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: [z\baL|  
    enableservice('AutomationServer', true) M  hW9^?  
    enableservice('AutomationServer') b3_P??yp  
    Bx\ o8k  
    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 LUxDP#~7

    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: 0\"#Xa+}8  
    1. 在FRED脚本编辑界面找到参考. &c "!Y)%G  
    2. 找到Matlab Automation Server Type Library ?7)v:$(G}  
    3. 将名字改为MLAPP |J`v w

    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。  wT19m

    1. 创建Matlab服务器。 M]k Q{(  
    2. 移动探测面对于前一聚焦面的位置。 !oXFDC3k  
    3. 在探测面追迹光线 f?^-JZ  
    4. 在探测面计算照度 rZ+4kf6S   
    5. 使用PutWorkspaceData发送照度数据到Matlab *k#"@  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ks phO-  
    7. 用Matlab画出照度数据 Z~h6^h   
    8. 在Matlab计算照度平均值 "(W;rl
