    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。 a[rUU'8  
    p~co!d.q/}  
    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: *[YN|  
    enableservice('AutomationServer', true) SX,z J`"  
    enableservice('AutomationServer') VMXXBa&  
    J>PV{N  
    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 ,99G2E v4c  
    /RmCMT  
    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: b(Xg6  
    1. 在FRED脚本编辑界面找到参考. B K;w!]  
    2. 找到Matlab Automation Server Type Library ]}l!L;  
    3. 将名字改为MLAPP Qq`\C0RZ

    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。 {`zF{AW8q

    1. 创建Matlab服务器。 \LXC269  
    2. 移动探测面对于前一聚焦面的位置。 rI789 q  
    3. 在探测面追迹光线 \ChcJth@o<  
    4. 在探测面计算照度 TZ2f-KI  
    5. 使用PutWorkspaceData发送照度数据到Matlab N9<eU!4>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 bm.H0rHR4  
    7. 用Matlab画出照度数据 q Q8l8  
    8. 在Matlab计算照度平均值 bb/MnhB  
    9. 返回数据到FRED中 r&DK> H
