    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。 ZU-4})7uSB  
    X<~k =qwA  
    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: N^ h |h  
    enableservice('AutomationServer', true) wfBuU>  
    enableservice('AutomationServer') [J)/Et  
    5=Kq@[(4  
    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 .!yWF?T8

    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: -(\1r2 Y  
    1. 在FRED脚本编辑界面找到参考. By?nd)  
    2. 找到Matlab Automation Server Type Library .4Qb5I2#  
    3. 将名字改为MLAPP ,< @,gZru

    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。 E?Zb~xk

    1. 创建Matlab服务器。 _urG_~q  
    2. 移动探测面对于前一聚焦面的位置。 *8$>Whr  
    3. 在探测面追迹光线 -7>^ rR V  
    4. 在探测面计算照度 }#yU'#|d  
    5. 使用PutWorkspaceData发送照度数据到Matlab WD15pq l  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "^;#f+0  
    7. 用Matlab画出照度数据 CO-Iar  
    8. 在Matlab计算照度平均值 t< sp%zXZ  
    9. 返回数据到FRED中 {(rf/:X!p
