    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。 yMJY6$Ct  
    igoUKDNiQ-  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: ,wI$O8"!j  
    enableservice('AutomationServer', true) 4 ^=qc99  
    enableservice('AutomationServer') W7j-siWJ  
    jJX-S  
    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 oj8_e xx

    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: e)(m0m\  
    1. 在FRED脚本编辑界面找到参考. gwf *M3(  
    2. 找到Matlab Automation Server Type Library 4yk!T  
    3. 将名字改为MLAPP nE~HcxE/

    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。 _cWz9 ;

    1. 创建Matlab服务器。 34@f(^d+^  
    2. 移动探测面对于前一聚焦面的位置。 !hBzT7CO  
    3. 在探测面追迹光线 CL~21aslI  
    4. 在探测面计算照度 ?=UIx24W  
    5. 使用PutWorkspaceData发送照度数据到Matlab C< :F<[H  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 UUzu`>upB  
    7. 用Matlab画出照度数据 z3RlD"F1  
    8. 在Matlab计算照度平均值 np>RxiB^
