    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。 ~YWQ2]  
    6H WE~`ok6  
    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: h_,i&d@(  
    enableservice('AutomationServer', true) ( 2E\p  
    enableservice('AutomationServer') T;a}#56{^  
    ag;pN*z  
    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 jZkcBIK2

    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: >rmqBDKaQ  
    1. 在FRED脚本编辑界面找到参考. >7T'OC  
    2. 找到Matlab Automation Server Type Library w4{<n /"  
    3. 将名字改为MLAPP x}I+Iggi

    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。 By",rD- r

    1. 创建Matlab服务器。 Y0dEH^I  
    2. 移动探测面对于前一聚焦面的位置。 ' ;FnIZ  
    3. 在探测面追迹光线 DGn;m\B  
    4. 在探测面计算照度 Eib5  
    5. 使用PutWorkspaceData发送照度数据到Matlab a;qryUyG  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 +RMSA^  
    7. 用Matlab画出照度数据 -[9JJ/7y
