    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。 FJ V!B&  
    II}3w#r4  
    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: iy,jq5uw  
    enableservice('AutomationServer', true) } |? W  
    enableservice('AutomationServer') G+W0X  
    0bI} s`sr  
    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 kiR+ Dsl

    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: lZhd^69y  
    1. 在FRED脚本编辑界面找到参考. y(Ck j"  
    2. 找到Matlab Automation Server Type Library CoQ<Ky}*  
    3. 将名字改为MLAPP `&)uuLn|

    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。 gK>aR ^*

    1. 创建Matlab服务器。 LRmH@-qP  
    2. 移动探测面对于前一聚焦面的位置。 }SBpc{ch  
    3. 在探测面追迹光线 222Mm/QN  
    4. 在探测面计算照度 & 0%x6vea  
    5. 使用PutWorkspaceData发送照度数据到Matlab  Y.v. EZ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 9/I|oh_ G  
    7. 用Matlab画出照度数据 85]3y%f9  
    8. 在Matlab计算照度平均值 ` @Tl7I\  
    9. 返回数据到FRED中 )i*-j =
